Multifunctional anemometric microsystem based on silicon carbide

Abstract

Abstract The results of optical methods for diagnostics of hot gas flows from an image are presented, taking into account the features of TV diagnostics of hot gas flows. The design of the SIC - universal anemometric Microsystem (UAMS) was proposed and investigated, and mathematical and thermal models of the pendulum - Microsystem were presented. A series of calculations and simulations were performed to estimate the degree of influence of temperature, gas flow velocity, and spatial orientation of the probe on the temperature field in it. It is shown that according to the conducted research, the gas flow rate has a very weak effect on the temperature distribution in the selected directions in the pendulum - Microsystem. For example, when the pendulum was longitudinally blown with air, the maximum temperature difference did not exceed 0.1 K. This indicates a high stability of the characteristics of the pendulum-SIC Microsystem.
