NUMERICAL STUDIES ON VARIATION OF PRESSURE AND VELOCITY AT INLET AND EXHAUST OF A TURBOJET ENGINE WITH FLUENT SOFTWARE

摘要

In the present study, the flow analysis of various parameters such as static pressure, velocity, total temperature, along inlet and exhaust passages of the turbojet engine has been computationally investigated. At first these variations is find out considering a normal rectangular shape combustion chamber and then take the actual shape combustion chamber and modeling it in GAMBIT and put the same boundary condition into this shape of combustion chamber. After that, comparing the variables between the two shapes of combustion chamber & plot the variation and the comparison graph of species. The results found out for each parameter computationally is compared with the values of the parameters of an actual shaped inlet and exhaust passage. There is a 4% deviation between the actual values and computational values.
