Formation and investigation of a stepped gas-layer model in measuring and diagnostic equipment supports

The article demonstrates the results of the development and research of an approach that allows constructing a computational grid of a thin stepped gas layer that provides load-bearing capacity in the supports of high-precision measuring and diagnostic equipment. Moreover, it is noted that traditional methods for automatic generation of the computational grid usually lead to distortion of the initial geometry and, as a result, to the impossibility of correct modeling of the gas flow.

The author suggests a method based on decomposing the model into simple bodies, which allows forming a computational grid of the correct structure with the required shape and orientation of the elements. An important component of the proposed methodology is a set of settings applied to the model in order to provide interband interfaces, adjust boundary conditions, as well as for subsequent initialization of the solution and ensure convergence in calculations in the ANSYS Fluent system.

In addition, the author presents the results that demonstrate the course of test calculations and validate the effectiveness of the proposed approach during the simulation of the lubricating gas layer.
