AB  - In this paper, a MATLAB computer model of the compression process is presented. The substance
being compressed is air which is considered to be an ideal gas with temperature-dependent specific
heat capacities. Two approaches are presented to describe the temperature-dependent properties of
air. The first approach is to use the ideal gas table data from Ref. [1] with a look-up interpolation
scheme. The second approach is to use a curve fit with the NASA Lewis coefficients [2,3]. The
computer model developed makes use of a bracketing–bisection algorithm [4] to determine the
temperature of the air after compression. This computer code is supplied to the students and discussed
after the students have performed a detailed hand calculation. Then, students are required
to modify the supplied computer program to solve additional problems.
The instructional approach outlined in this paper accomplishes several objectives. First, this computer
work serves as a connection between first-year, computer-tools courses and engineering science
courses. At Indiana University-Purdue University FortWayne, students take a two-credit hour
computer tools course in which they learn MATLAB and then take a two-credit hour programming
course in which they learn C/C++ with an engineering emphasis. After completion of the courses,
students are often eager to apply their skills to engineering problems. Unfortunately, the opportunities
to utilize these skills are limited and students often question why they are required to take
the computer classes. More exercises need to be developed to utilize and reinforce the computer
skills. Second, the computer implementation allows students to easily vary the thermodynamic
parameters so that students can develop a deeper appreciation of the limitations associated with thermodynamic assumptions such as the constant specific heat approximation. Third, the flexibility
of the model allows for realistic extensions to the original problem, such as the incorporation
of heat loss from the compressor and compressor efficiency. As students modify the provided
computer code they develop additional insight and familiarity with thermodynamic equations and
concepts. Finally, in later courses, the computer model can be modified to investigate more complicated
situations, such as multistage compression with intercooling [5] or the gas turbine cycle [6].
Examples of how these objectives are achieved are provided and discussed.
