Abstract

A computer model of the isentropic compression of a gas with temperature-dependent specific heat capacities is presented. Both tabulated data and curve-fits are used to describe the temperature variation of the thermodynamic properties, and a bracketing-bisection algorithm is used to determine the temperature of the air after compression. Students are provided with an example computer code from which to begin. Thus, the approach as described in this study reinforces programming concepts from previous computer courses, without requiring too much effort by the students. Three exercises are presented that make use of this computer model at different levels in the curriculum.
