Discharging phenomena with involving nanoparticles and external force

To reach the lowest time for discharging process, not only the configuration of tank and material properties but also the external forces can be helpful. Among various approaches, using nanomaterial with wavy wall as well as insertion of Lorentz forces has been examined in current article. Galerkin approach was successfully applied for current modeling and impacts of active factors were exhibited. Direct relation of needed time and A shows that conduction rises with augment of A while the volume of PCM is not changed. Time reduces about 6.96% with rise of A in presence of Ha. Providing greater conduction mode with rise of Ha must be helpful to decline the need time. At A = 0.1, m = 5.7, augmentation of Ha from 0 to 20 leads to decline the time from 250.7 s to 247 s. At Ha = 20, A = 0.3, required time changes from 250.7 s to 229.8 s with rise of m. This behavior is due to higher k_nf of platelet shape. Rise of time augment the solid fraction but energy stored reduces.
