Design and Thermal Analysis of Hydrogen Gas Turbine

Abstract

This study takes a look at the design process of the air intake system of the Hydrogen gas Turbine Inlet Manifold. Differences in turbine outputs and applications require different designs of intake-air manifolds in order to achieve the best volumetric efficiency and thus the best turbine performance. In the present work, the flow characteristics of hydrogen gas flowing in various designs of air-intake manifold will be studied. The study is done by three dimensional simulations of the flow of air within two designs of air-intake manifold into the turbine by using commercial CFD software, ANSYS. The simulation results are validated by an experimental study performed using a flow bench. The study reveals that the variations in the geometry of the air-intake system can result in a difference of up to 20% in the mass flow rate of air entering the combustion chamber.

The design will be done in a 3D software Catia and analysis carried in FEA software called Ansys.
