Effect of Initial Grid's Size in Thermal Diffusion Simulation

Abstract:

The thermal diffusion similitude should be well considered during the numerical simulating of its distribution in power plants or nuclear power stations. The distribution near the waterspout is well related to the initial grid’s size. The bigger the initial grid is, the faster the thermal diffusion. Reasonable initial grid should be related to thermal discharge and flow velocity. Five different grid’s sizes are adopted to simulate the constant diffusion phenomenon in a rectangle water channel, the currents near the waterspout, the thermal diffusion near or away from the waterspout are discussed in this paper, and a rational size of initial grid is proposed to relative researchers.
