Effects of Pressure Drops on the Performance Characteristics of Air Standard Otto Cycle
Figure 4
Power output relative to its maximum value versus efficiency is plotted for different values of loss coefficients (pressure drop at point 1β, pressure drop at point 3β, compression isentropic efficiencyβ, expansion isentropic efficiency , and heat leak coefficientβ). The loss coefficients' values are (in the same order appeared above) (a) 1, 1, 1, 1, 0; (b) 0.8, 0.8, 1, 1, 0; (c) 0.6, 0.6, 1, 1, 0; (d) 0.6, 0.6, 0.97, 0.97, 0; (e) 0.6, 0.6, 0.97, 0.97, 0.05; (f) 0.6, 0.6, 0.97, 0.97, 0.1; (g) 0.6, 0.6, 0.97, 0.97, 0.5.
