Numerical diffusion

• abstract: Numerical diffusion is a difficulty with computer simulations of continua (such as fluids) wherein the simulated medium exhibits a higher diffusivity than the true medium. This phenomenon can be particularly egregious when the system should not be diffusive at all, for example an ideal fluid acquiring some spurious viscosity in a numerical model.

双语例句

• Without repeated interpolations such as in ELM, the Particle-tracing Method reduces the numerical diffusion quite a lot.

• To reduce the influence of the numerical diffusion on the computational results, such as decreasing the grid size has been used.

给出分离器内速度矢量图，减小数值扩散强旋流动影响采用减少网络尺寸等措施。

• Standard numerical methods solving these equations often produce nonphysical oscillations, and upwind methods usually cause excessive numerical diffusion which smear the sharp fronts.
