The principle of anisotropic heat diffusion is adopted to develop a mathematic model of pointcloud's smoothing. A pointcloud can be considered as a field of temperature field, boundary as adiabatic. So the smoothing is only on the local area and makes a good balance between moving noise ...
The impact of the inner structure and thermal history of planets on their observable features, such as luminosity or magnetic field, crucially depends on the poorly known heat and charge transport properties of their internal layers. The thermal and elec

Simplified models were obtained by considering an average diffusion coefficient of all ions, while diffusion transport of H+ and OH− was neglected. The film theory also was usually adopted to describe the mass transport process. Estimated kinetic expressions of CaCO3 disposition at low and high ...
The heat flux (actually, the flux of enthalpy) 𝑞˙q˙ in the direction of the temperature inhomogeneity 𝑥3x3 can be decomposed into the contribution of thermal diffusion, convection by fluid velocity, and transport associated with the particle motion. All these contributions are maximum in ...
As cities and their population are subjected to climate change and urban heat islands, it is paramount to have the means to understand the local urban climate and propose mitigation measures, especially at neighbourhood, local and building scales. A fram
For the same meshing zone, a structured mesh is more economically and efficiently reduces false diffusion than an unstructured mesh. Therefore, a structured mesh was used in the calculation domain in this study. Figure 2 shows the grid in the entire computational domain and local grid size in ...
