Abstract
This study is concerned with the development of a computational fluid dynamic (CFD) model for the OSU (Ohio State University) Rate of Heat Release Apparatus. The standard OSU reactor is about 1.4 m long with a rectangular structure and a conical exhaust region (chimney) for flow development and burning of the specimen induced by radiant heating and pilot flames. The chimney at the top of the reactor includes cooling flow channels along the chimney wall. A comprehensive computational fluid dynamic model for the OSU reactor (that considers the geometric details of the reactor) is now under development using ANSYS FLUENT. The validated model will serve as a benchmark for providing uniformity in predictions of the OSU reactors located in different laboratories. A validated model will also provide better understanding of the flow and heat transfer characteristics in the OSU reactor. The OSU calorimeter and the cone calorimeter are test devices that measure the rate of heat release from burning materials. While comparisons between data generated from the two instruments is found in the literature, no systematic attempt has been made to show conformity, of results between the two test methods. In addition, the OSU calorimeter is in frequent use by a government transportation agency for measuring the rate of heat release of materials used in the interior of passenger aircraft. There are maximum allowable values of peak heat release rate of such materials and accurate measurement of these rates is imperative.
