Numerical and Experimental Investigation of Motor Pressure Effect on Thermochemical Erosion of Graphite Nozzle in Solid Fuel Engines
Using heat shield, especially in throat area has a significant effect on combustion chamber pressure and thermal efficiency of solid fuel engines. Precise prediction of the regression of throat area for different pressures, will lead to optimal design of the motors, specifically for those of long burnout times. In this work, erosion of graphite nozzles employed in solid propellant motors with a...
متن کاملHeat Transfer Based Numerical Investigation of Aircraft Cabin Environment from Various Inlet Conditions
A numerical investigation was conducted to study the heat transfer in an aircraft cabin and the effects of air distribution under different angle and inlet velocity conditions. The Reynolds-averaged Navier–Stokes equations and the low Reynolds number turbulence model were used to simulate the airflow in the cabin. Mathematical statistics was used to process the relevant data, and statistical re...
متن کاملThermodynamic Investigation and Optimization of a Power Generation System Based Solid Oxide Fuel Cell Using Taguchi Approach
Fuel cells directly convert chemical energy into electrical power using electrochemical reactions. Solid oxide fuel cell (SOFC) is one of the high-temperature fuel cells that propose a promising future from the standpoint of power generation. In this study, optimization of an SOFC system is performed using Taguchi approach after verification of the model in compare with experimental results. Cu...
متن کاملA Numerical Investigation of the Thermal Stresses of a Planar Solid Oxide Fuel Cell
A typical operating temperature of a solid oxide fuel cell (SOFC) is quite high above 750 °C and affects the thermomechanical behavior of the cell. Thermal stresses may cause microstructural instability and sub-critical cracking. Therefore, a joint analysis by the computational fluid dynamics (CFD) and computational structural mechanics based on the finite element method (FEM) was carried out t...
