Question

Assume the liquid film in Example 5.9 is not isothermal but instead has the following distribution TðyÞ T 0 ðT w T 0 Þ 1 yh where T 0 and T w are respectively the ambient temperature and the wall temperature The fluid viscosity decreases with increasing tem perature and is assumed to be described by μ μ 0 1 aðT T 0 Þ with a 0 In a manner similar to Example 5.9 derive an expression for the velocity profile

Answer 1

The velocity profile is

Pg(hy - y^2/2)sintither/u
