Thermal modes simulation of heat exchangers networks having turbo-machines

摘要

In recent years rather many papers have appeared on the subject of steady-state analysis of flow and pressure in the piping systems. However, there exists a class of systems where thermal analysis is a problem of great importance. Airconditioning and ventilation ship systems being networks of heat exchangers and turbo-machines (air cycle machines, in particular) are the examples of the such belonging to the class. In the paper mathematical model and method are presented for thermal analysis of the systems where recuperative heat exchangers of arbitrary configuration (flow arrangement, a number of flow passes) and multistage air cycle machines are available. The object-oriented data architecture of the model is elaborated.
