engine and does no thermodynamic work on the flow. Finally, the flow comes through the nozzle where no thermodynamic work is performed on the flow by the nozzle. Third, the compressed air is combined with fuel and is ignited within the combustor. Entering the compression angela teichert dissertation ratio is optional and if it is not entered, the program will find the maximum value for Vf and the compression ratio that will give the maximum value. The process within the combustor is assumed to be isentropic. Jet Propulsion Essay, Research Paper, jET propulsion, thermodynamics ME-304. Flow through the diffuser, nozzle, compressor and combustor is isentropic.

Once the user has made their selection they will be prompted for the essential values needed to calculate. The calculations are made assuming idealized conditions. This is done by injecting additional fuel into the gas exiting from the turbine.
The essay about blind man resulting high temperature fluid is used to turn the fourth component of the turbojet, the turbine. On Microsoft Windows systems, make sure the path containing the thermo. M and findvft3.m files is in the matlab path and then type thermo at the matlab prompt. Next, the turbine is used to extract energy from the heated flow coming from the burner. The temperature remains constant through the nozzle while the pressure and velocity of the flow will change as dictated by the design of the nozzle. The program is a matlab script so the first thing that must be done to run it is to start matlab. The engine is operating at steady state. Air behaves as a compressible, ideal gas.
