Computer model of catalytic combustor/Stirling engine heater head. [HET computer code]
The HET catalytic combustor computer model was developed as an aid in the solution of problems related to catalytic combustion applications for various systems such as boilers and gas turbines. The HET model differs from previous models in that it can handle the high temperature effects of catalytic combustion where bed radiative heat transfer and flame type phenomena are important by including gas phase reactions and wall radiation terms. For a balance between accuracy and economy of operation, the code utilizes a quasi-one-dimensional model. In this project, the HET code is used as a basis for examining different concepts utilizing catalytic combustion for Stirling engine heater heads. The theoretical foundations upon which the calculation methods of the Stirling Engine HET Code program are based are summarized. An attempt is made to present these fundamentals in a fashion most appropriate to a user unfamiliar with the code. To this end, and in the interest of brevity, explanations tend to be nonrigorous and perhaps somewhat heuristic. In discussing each type of problem treated by the program, the pertinent governing equations are developed and it is shown that these relations are sufficient to determine the unknown quantities for that particular problem. Since all problems related to the Stirling engine are essentially solved by a modification of the basic HET code the basic HET code is described first. Then, how the basic code is modified for each Stirling concept is discussed. Calculations and correlations for radiation view factors and transport properties are then discussed. Code input instructions, sample problems, and programs and subroutines are included.
