Abstract: 

Current article devoted to simulation of passive techniques impact on reduction of solidification time within a tank with two cold surfaces which are connected to cold fluid flows. Design of current unit is based on NEPCM and wavy shape of inner wall. Addition of powders can enhance the discharging rate and it is more sensible for greater shape factor. In view of energy absorbed, time of solidification is very important. Complete discharging occurs when all liquid convert to solid. Outputs demonstrated that the times required for full solidification augments with reduce of shape factor and similar behavior was observed for amplitude of wavy cylinder. Faster solidification can take place as a consequence of greater shape factor.
