Numerical and Experimental Investigation of Wire Cloth Heat Exchanger for Latent Heat Storages

Latent thermal energy storages (LTES) offer a high storage density within a narrow temperature range. Due to the typically low thermal conductivity of the applied phase change materials (PCM), the power of the storages is limited. To increase the power, an efficient heat exchanger with a large heat...
