Genuinely Multidimensional Kinetic Scheme For Euler Equations
This work provides a new multidimensional framework for solving Euler equations that can be integrated with various numerical methods, offering potential improvements in computational fluid dynamics for shock and discontinuity capturing.
The authors developed a genuinely multidimensional kinetic scheme for Euler equations, demonstrating improved shock capturing and isotropic flow feature resolution compared to the Kinetic Flux Vector Splitting Method.
A new framework based on Boltzmann equation which is genuinely multidimensional and mesh-less is developed for solving Euler's equations. The idea is to use the method of moment of Boltzmann equation to operate in multidimensions using polar coordinates. The aim is to develop a framework which is genuinely multidimensional and can be implemented with different methodologies, no matter whether it is in finite difference, finite volume or finite element form. There is a considerable improvement in capturing shocks and other discontinuities. Also, since the method is multidimensional, the flow features are captured isotropically. The method is further extended to second order using 'Arc of Approach' concept. The framework is developed as a finite difference method (called as GINEUS) and is tested on the benchmark test cases. The results are compared against Kinetic Flux Vector Splitting Method.
