Abstract
BackgroundAcoustic flows are the rotational flows that are generated near solid surfaces and vibrating components, as well as near boundary walls in a high-intensity sound field. By making the flow oscillate, this type of flow can be a good way to improve HT. Besides, phase change materials provide high cooling in a short time because they absorb the latent heat of their melting during melting. MethodThe use of the phase change material and adding some pulsing function of inlet flow have been considered to investigate the battery's performance. To this end, the finite volume method, along with interface mesh and grid adaptation techniques, has been used to achieve more accurate results. FindingThe comparisons of the obtained results were made to the existing data, and after ensuring the numerical methodology, four functions were used to investigate the effects of variations in inlet velocity. The results showed that different kinds of pulsation flows have different qualities and ways to improve HT in different situations. For instance, the sine profile helps the average temperature of the PCM unit reach the maximum value in approximately 50 percent less time.
