Abstract
This study presents Computational Fluid Dynamics (CFD) simulations of a thermal gyroscope based on the deflection of a gas jet by the Coriolis force, A warm gas jet is generated by a pressure difference within a mirofluidic channel and is directed upon temperature detectors. The differential temperature between the detectors is related to the rotation applied to the system. The study analyses several parameters such as the gas velocity, detectors location but also different geometries of the microfluidic channel in order to find the best sensitivity, In addition the simulations have been used to determine a set of working conditions that allows avoiding the Coanda effect while improving the global sensitivity of the system.
