Experimentally-validated numerical studies of thermal performance enhancement of latent thermal energy storage systems with periodically reciprocating flow

The effects of periodic reversal flow direction a heat transfer fluid (HTF) on the rate in latent thermal energy storage system (LTESS) are numerically investigated for consecutive melting and freezing cycles phase change material (PCM). Numerical results validated with experimental measurements. Parametric studies performed, where different parameters that affect performance LTESS varied independently. these variations periodically reciprocating unidirectional HTF studied. Periodically increased uniformity temperature gradients throughout PCM both cycles, compared to flow. Increasing HTF, increases relative enhancement cycles. An optimal reciprocation period which is dependent other parameters, noticed produce maximum fusion or conductivity nonlinearly.
