Kinetic particle model and heat flow
WebIn this section, we will describe the basic approaches for plasma modeling and, in particular, approaches that are based on numerical simulations. Two basic approaches were developed in plasma physics and engineering. The first one is based on the fluid description of plasma and is solved numerically by applying the magnetohydrodynamic equations. Web1 feb. 2024 · Numerical investigation of a steam methane reforming process was performed from point of view to understand the heat flows inside a catalyst particle. To verify the numerical results, a new method based on the thermal conductivity equation has been developed to determine the temperature distribution inside the catalyst particle. The …
