Popis: A user-friendly heat transfer/thermal modeling code, LinerTherm, has been developed for rapid analysis of aircraft exhaust liner cooling systems. Most of the thermal modeling codes on the market today fall into one of two categories either they are complex 3-D codes requiring significant engineering resources or they are simple conduction models that lack advanced convection capabilities required for high performance aerospace and propulsion cooling applications. In the high-tech field of aerospace propulsion, it is necessary that rapid modeling of complex thermal systems be accomplished to enable the trade studies required to optimize aircraft cooling liner designs for weight, cost, and performance. This code performs detailed thermal analysis of gas turbine exhaust liners used in the augmentor and nozzle and includes cooling capabilities for impingement, multi-hole film-cooled, slot filmcooled, and convectively cooled liners. Its simple user interface provides the capability of performing quick trade studies for a vast array of cooling liner designs, including a wide selection of included materials.
