Unified computational method for design of fluid loop systems
Abstract
Various kinds of empirical formulas of Nusselt numbers, fanning friction factors, and pressure loss coefficients were collected and reviewed with the object of constructing a common basis of design calculations of pumped fluid loop systems. The practical expressions obtained after numerical modifications are listed in tables with identification numbers corresponding to configurations of the flow passages. Design procedure of a cold plate and of a space radiator are clearly shown in a series of mathematical relations coupled with a number of detailed expressions which are put in the tables in order of numerical computations. Weight estimate models and several pump characteristics are given in the tables as a result of data regression. A unified computational method based upon the above procedure is presented for preliminary design analyses of a fluid loop system consisting of cold plates, plane radiators, mechanical pumps, valves, and so on.
