WebAn Otto cycle having a compression ratio of 9:1 uses air as the working fluid. Initially P1= 95 kPa, T1= 17 oC, and V 1= 3.8 liters. During the heat addition process, 7.5 kJ of heat are added. Determine all T's, P's, ηth, the back work ratio, and the mean effective pressure. WebResearch interests fields and professional achievements: 1. Combustion process modelling; - kinetic mechanisms validation calculations( ignition delay, laminar flame speed, diffusion flame structure, detonation properties of gas mixtures); - 1D shock tube experiments simulation; - kinetic mechanisms reduction; - calculation of the emission absorption …
WebThis volume treats air as a single fluid, rather than as a mixture of oxygen and nitrogen, enabling you to design using accurate air properties - not well characterized in extant publications. This is why your research demands Thermodynamic Properties of Air. WebIf the working fluid is assumed to be a perfect gas with the properties of air at room temperature, determine the following: a) specific impulse b) mass flow rate c) throat diameter d) exit diameter e) kinetic energy production rate for the engine (given the number is both kW and Hp) For the same nozzle find: f) thrust in space
Webcompression process, 44.5 kJ of work is done on the air. The cylinder is fitted with a cooling water jacket all around its outer wall. The cooling water jacket contains 1.75 kg of liquid water. The water is initially at a temperature of 25 C and an absolute pressure of 1 bar (State 3) at the start of the air compression process. Heat
