Effects of Initial Conditions on Oscillatory Flow in an Oscillating Heat Pipe
Effects of initial conditions on the oscillatory flow in oscillating heat pipes (OHPs) are investigated
numerically. Initial vapor temperature, pressure and liquid displacement are in consideration. Three test cases
are solved with different initial condition settings. Liquid displacement and vapor temperature tendencies are
compared to find which initial condition lead to the best heat transfer performance in all test cases. Fast Fourier
transform is employed to calculate the frequency based on liquid displacement. The results show that initial
condition has significant effect on oscillating heat pipe performance and keeping initial condition uniform is
an effective way for heat transfer enhancement of the system.
