Study the Performance of a Dynamic Wall Heat Exchanger Using Computational Fluid Dynamics

Thermal systems in small devices like cooling electronic chips require efficient technologies with diameter channels. These have laminar flow and disrupted boundary layers, leading to high pressure drop values. To ensure sufficient limit coolant temperature, a possible solution is dynamically deform one channel wall mimic pumping disrupt creating peristaltic effect, called dynamic heat exchanger. The aim of the present numerical study explore effects different operating parameters exchanger on transfer performance. In our we varied (amplitude vibration A, frequency f, minimum gap between upper lower H difference P) observed how it affects performance terms mass rate (water) coefficient. A crucial finding that distribution isotherms streamlines adequate, significant when relative amplitude high. Additionally, this type can generate substantial even minimal externally applied pressure.
