Abstract

The present study aimed to design a subsonic wind tunnel and compare the numerical and experimental results to ensure the accuracy of the design that has been manufactured after the simulation process. The Euler equations of the two-dimensional inviscid flow were solved using a finite volume approach by utilizing an algorithm developed in MATLAB. The values of velocity in the x direction (u), velocity in the y direction (v), static and stagnation pressure, and density of the flow were computed at each point of a (100 X 32) mesh with a time step of 0.002 X 10−7 for 1000 iterations. The mass flow rate FMR value of one, the uniformity of the flow in the test section, which is obvious in the fluid properties contours, the pressure value of 105 N/m2 that has been constant at inlet and outlet, and the good agreement of numerical and experimental results between pressure and velocity variations along the centerline of the subsonic wind tunnel are all indicators of the accuracy and computation efficiency of the analysis method that has been used.
