Modeling dynamics of pressure fluctuations in a microchannel heat exchanger covered with a wire mesh membrane

Pressure and mass flow fluctuations in a system consisting of a microchannel two-phase heat exchanger with wire mesh covering and overflow chamber were modelled by employing mass, momentum, and energy balances on the fluid in mesh volume. These fluctuations are a result of the alternate wetting and...
