Analysis of the flow past the screw with the use of numerical and experimental simulation

The paper presents the study results of the aerodynamic characteristics of a real propeller. The purpose of the research is to select a method of the simulation of the flow around the screw in the absence of an incident flow. Experimental and numerical research methods are used. The flow characteristics around the screw are obtained experimentally in a wind tunnel. Computer simulation in the software complex ANSYS CFX is applied as a numerical method. As a result, a flow pattern, consistent with well-known studies, is obtained. The obtained values of the propeller thrust, calculated in the process of numerical simulation, are comparable with the experimental data. The results of the work confirm the possibility of using the CFD method to determine the flow characteristics of the propeller, taking into account its geometric parameters.
