KMUTT Annual Research

KMUTT Annual Research Abstracts 2005 beneficial to the traffic noise impact investigation and assessment of highway construction projects. In this study, nine types of vehicle on highway in Thailand are under investigation. The neural network analysis with genetic algorithm (neuro-genetic) is applied to analyze for the best mathematical function of each vehicle type's model. The analysis data is then trained in order to improve the efficiency of the analysis by screening out some of the scattered data with the utilization of accuracy interval technique. The new set of data is reanalysis with neuro-genetic in order to get the final mathematical model of each type of vehicle. Finally, these new basic noise models for all of the nine vehicle types in Thailand can provide the good results in the statistical goodness-of-fit test. Therefore, they can be used effectively for the farther analysis of the main highway traffic noise of Thailand. IC-064 L EQ (20S) BASIC NOISE LEVEL FOR FREE FLOW VEHICLE IN THAILAND Pichai Pamanikabud, Marupong Tansatcha The 2005 IASME/WSEAS International Conference on Energy, Environment, Ecosystems and Sustainable Development, July 12-14, 2005, Vouliagmeni, Athens, Greece, pp. 1-4 The basic noise model is the primary noise model for each vehicle type in the traffic stream. It is used as a basic model in the development of the main highway traffic noise simulation model of the whole highway section. This basic noise model is normally different from country to country due to the characteristics of local vehicles and driving conditions of each particular country. This study aims at the developing of basic noise model for each vehicle type in Thailand. These basic noise models based on the equivalent sound pressure level in 20 seconds time period - L eq (20s) for free flow traffic condition. In this study, nine vehicle types on way in Thailand are used. The L eq (20s) can cover the range of noise levels of all vehicle types better than previous models, which are in form of L max and L eq (10s). Therefore, this new analysis technique of basic R model can predict noise level of each vehicle type closely to real situation on highway. It can also be applied to build the basic noise model of vehicle in other places or countries. 99 IC-065 ACCELERATED BASIC NOISE LEVEL OF INTERRUPTED FLOW TRAFFIC Pichai Pamanikabud The 15 th International Road Federation World Meeting 2005, June 14-18, 2005, BITEC, Bangkok, Thailand, pp. 1-6 The objective of this research is to study and develop the model that can represent the characteristics of basic noise level of vehicular traffic in the interrupted flow traffic condition that generally appears in the urban area. This paper presents the research work that aimed, at the development of basic noise level of interrupted flow traffic in the acceleration part of the stop-and-go pattern or from the stop line onward for vehicles in Thailand. Eight types of local vehicle are under investigation, namely, automobile, light truck, medium truck, heavy truck, semi-trailer and full-trailer truck, bus, motorcycle, and tuk-tuk (motor-tricycle). Field data are collected for each type of vehicle in the accelerating condition from the stop line. Integrated sound level meters are placed at the distances of 15, 30, 60, and 120 m respectively from the stop line with the set back distance of 15 m from the centerline of measuring traffic lane. The maximum noise level (Lmax) of a single passing by vehicle is collected at each of these four locations together with the vehicular spot speed at that particular location. Statistical analysis is then given in order to analyze the relationship between Lmax generated by each vehicle type and the spot speeds which represent the accelerated part of basic noise model of interrupted flow traffic. From the studied results, the basic noise level model developed by this study provides the highly Significant in statistical goodness-of-fit test of the correlation between noise level in Lmax and the vehicular spot speed. Therefore, they can be used effectively for further development of the main interrupted flow traffic noise model. IC-066 SIMULATION OF ELEVATED MASS RAPID TRANSIT NOISE Pichai Pamanikabud The 23 rd Conference of ASEAN Federation of Engineering Organizations (CAFEO-23), December 8-9, 2005, Vientiane Capital, Laos This study is aimed at the analysis and simulation of noise generating by the cruising International Conference

100 elevated mass rapid transit (MRT) in the city of Bangkok. The straight sections in between stations of the Bangkok Transit System (BTS), which is the first viaduct MRT system in Bangkok, are used for this study. Data collection is done for all noise generating parameters on the buildings along the sides of this BTS system. These data consist of the BTS trains noise level measured in Leq 1 hour period at the locations on high rise building along the BTS lines on Sukhumvit, Phaholyotin and Silom roads. Volume in term of train number together with the cruising spot speed of each train is also collected during this 1 hour period. The physical dimensions of vertical and horizontal distances of centerline of train track to the point of noise meter on the building are also measured using surveying equipment, so the distance from centerline of train track to noise meter can be later calculated. These data collection are applied for both sides of train tracks in both of BTS lines. All these noise generating parameters are analyzed in order to see their correlations with the noise level. The noise simulation model is then built from this relationship. The final model from this study can provide a significant goodness-of-fit between the predicted results from the model and the measured data with coefficient of determination R equal to 0.841. Therefore, this simulation model of elevated mass rapid transit noise can be effectively used for further analysis and prediction of the viaduct BTS noise in Bangkok, and also can be used for all other elevated MRT with similar features. IC-067 THROUGH-FLOW ANALYSIS OF CENTRIFUGAL FAN USING CFD Wanchai Asvapoositkul, Teerasak Chomcherd, Arthit Supachanyawat, Jamorn Wongsuksamerjai The 8 th Asian Symposium on Visualization (8ASV), May 23-27, 2005, The Empress Hotel, Chiangmai, Thailand, pp. 212-213 In this paper, a backward-curved centrifugal fan of 400 mm diameter with 11 blades is analyzed using CFD. The flow patterns throughout the fan are visualized by numerical flow simulations (a commercial code: CFX from AEA Technology), and the fan's performance has been compared to the AMCA experiment result. The computed fan characteristics correspond quite well and give a detailed insight the flow structures. These help significantly to KMUTT Annual Research Abstracts 2005 understand the flow and to improve the design of future centrifugal fan. The improvement efficiency can be obtained by the reduction of the flow losses. The intensity of secondary flows has an important effect on the flow filed at the exit of the impeller. Therefore the impeller should be redesigned to suppress meridional component of secondary flow. The corner flow separation was also observed. Then suppression of corner separation at the cut off has to be done. High mixing loss observed at the volute outlet was generated mainly in this region due to the flow non-uniformity. It was much high at the exit of volute casing. In summary the apparently modifications included improvements fan impeller, suppression of corner separation and exit flow uniformity. IC-068 EFFECT OF ROTATION SPEED ON MICROSTRUCTURE OF NI-RICH TI-NI SHAPE MEMORY ALLOYS Anak Khantachawana The 8 th Asian Symposium on Visualization (8ASV), May 23-27, 2005, The Empress Hotel, Chiangmai, Thailand, p. 183 Shape memory alloys (SMAs) are wellknown for their large recovery stress and deformation. In the present study, the Ni-rich Ti- Ni SMAs were fabricated by a new technique called "Rapid solidified melt-spinning method". The specimens fabricated have ribbon shape with thickness around 20 µm. Ni-content was varied from 50at% to 55at% while the rotation speed of Cu-roller was also varied from 2500rpm to 7500rpm in the fabrication process. The equiatomic alloy composition revealed the crystalline structure with a strong fiber texture irrespective of rotation speed. On the other hand, in the specimens with Ni-content above 51at%, it is seen that amorphous structure can be easily confirmed with increasing rotation speed. Fig. 1 shows Bright-field image and diffraction pattern with the beam direction parallel to [100]B2 for a Ti-51at%Ni as-spun ribbon. Nonequilibrium plate precipitates with a radius of about 10nm located uniformly along {100} of B2 phase. Besides, fairy strong streak are seen along [001] and [010] the [100] diffraction pattern. Then, this strong streak must come from the thin plates lying on {100} planes. It is considered that these fine precipitates International Conference
