Authors:       Hoai Nguyen, Minh Man Pham
Abstract:     Computational fluid dynamics (CFD) is one of the common applications of fluid mechanics, numerical methods and algorithms are used to solve problems related to fluid flow. Nowadays, computers are used to simulate the interaction of liquid and airflow in a region defined by boundary conditions, however, in many cases, the algorithm stops at only approximate. Along with the on-going development of research work, many open source software was created to improve the accuracy and speed in situations simulating complex flows. In this paper, supersonic flow and shockwave are simulated in a flat domain size determined by using OpenFOAM. Since then, the theoretical basis of the problem is built, while some parameters, such as: temperature, pressure, velocity, and so on is optimized. Through the process of calculation and testing, simulation results are determined accurately and clearly. The simulation results show, when the airflow moving over the shockwave, parameters of supersonic flow changed of great value. This is the basis for identifying the movement of the airflow and optimizes the design of equipment in fact.
