Example Embodiment

[0027] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0028] The present invention selects an appropriate equilibrium distribution function on the basis of the standard CFD technology-based fluid design method to make it meet the maximum entropy of the system in a statistical sense. The discrete H entropy function is generally defined as: where ωi is Gauss- Hermiter integral weight. At the same time, for the entropy lattice Boltzmann equation, the relaxation time parameter γ must be adjusted to satisfy the H function theory and make the H function satisfy the extreme value condition. The monotonicity constraint of the H function is composed of two processes: 1) The deviation of the single particle distribution function from the equilibrium state. During this process, the H function remains constant; 2) The entropy function increases due to the consumption of walking. The relaxation time parameter in ELB...

Description

technical field [0001] The invention relates to the application of computational fluid dynamics, in particular to a fluid system based on CFD technology and a design method thereof. Background technique [0002] The so-called CFD, the English full name (Computational Fluid Dynamics), that is, computational fluid dynamics, is a branch of fluid mechanics, referred to as CFD. CFD is the product of the combination of modern fluid mechanics, numerical mathematics and computer science, and is a fringe science with strong vitality. It uses computer as a tool and applies various discrete mathematical methods to conduct numerical experiments, computer simulations and analytical research on various problems in fluid mechanics to solve various practical problems. [0003] Computational fluid dynamics and related computational heat transfer. The principle of computational combustion is to use numerical methods to solve nonlinear simultaneous differential equations of mass, energy, comp...
