Effects of Pressure Drops on the Performance Characteristics of Air Standard Otto Cycle
Figure 3
Relative power output to its maximum value versus compression ratio is plotted for different values of loss coefficients (pressure drop at point 1โ, pressure drop at point 3โ, compression isentropic efficiencyโ, expansion isentropic efficiency , and heat leak coefficientโ). 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.
