Abstract

The new code has been developed for simulating the freezing of nanomaterial with water base PCM. This code was based on Galerkin approach and style of grid depends on position of solid first layer. The two surfaces have been maintained at cold temperature and fins have been mounted to increase the space of cold area. The single phase techniques for deriving the properties of nanomaterial were developed. As powders were applied, the needed time augments from maximum value (1390s) to minimum value (11038.49s). This means that with selecting the powders with shape factor of 8.6, the freezing time declines about 25.28%. Besides, changing shape can reduce the time about 6.27%. As fraction increases to twice value, the speed of process increases around 12.93%.
