Flow-type static pressure probe simulation using ANSYS58_11.pdf

The article deals with the results of the flow-type air pressure probe simulation during various turbulent conditions using the ANSYS software. Based on the findings, conclusions were drawn up that when simulating air pressure probes, it is required to set turbulent flow characteristics, to select k-epsilon turbulence model, mesh size of 0.025 mm in the calculation with double precision. The dependence of convergence coefficient k of data after simulating and testing flow- type air pressure probes on turbulence intensity parameters is calculated. The results of aerodynamic tests of a flow-type static-pressure tube in the wind tunnel of Ulyanovsk Instrument Manufacturing Design Bureau, JSC, and its simulating in the ANSYS software are compared taking into consideration the convergence coefficient.
