Methodology<br />

Boundary Conditions to Simulate the <strong>Fogging</strong> <strong>and</strong> <strong>Defogging</strong><br />

O min Start condition • Temperature: 25 ºC<br />

• Relative Humidity: 95%<br />

• All the lamps off<br />

0 min → 30 min Heating • Temperature: 25 ºC<br />

• Relative Humidity: 95%<br />

• All the lights on with the direction indicator flashing at<br />

the frequency 1,5Hz.<br />

• Engine working temperature: 90ºC<br />

30 min → 35 min <strong>Fogging</strong> • <strong>Water</strong> temperature (focusing on external lens): 25 ºC<br />

• Temperature: 25 ºC<br />

• Relative Humidity: 100%<br />

• All the lamps off<br />

35 min → 60 min <strong>Defogging</strong> • Temperature: 25 ºC<br />

• Relative Humidity: 95%<br />

• All the lamps off
