Prediction of batch heat transfer coefficients for pseudoplastic fluids ...

plastic fluids. These papers are quite Ibnited in scope.
The purpose of this thesis is to develop a design correlation
(based on the analysis of a flow model and experimmtal
data) for the prediction of batch heat transfer coefficients
for pseudoplastic fluids.
SCOPE OF THESIS
& -·e -
T'HO types of correlation were developed..
One is an
equation based on a dimensional analysis of the equations
describin-.g a simplified flo1-l modeL.
The second is a
modification of the l'JeHtonian correlation using an apparent
viscosity developed by A. B. Metzner, et ale (122, 125).
The experimental variables studied cover a fairly
l-lide range..
Four types of impellers Here used:
Type
Flat bladed paddle
Disk and vane turbines
Marine propeller
Anchor

The heat transfer surface Has the vessel wall (Some
papers on Ne1tJtonian fluids have studied coils). Both
Ne1tTtonian and pseudoplastic fluids were studied.
