Abstract
A special materials processing furnace is being developed for the forthcoming Spacelab missions to study the solidification under closely controlled conditions of various sample materials in the absence of gravity. The samples are to be rod shaped and subjected to both heating and cooling simultaneously. The thermal model is based on a developed Thermal Analyzer computer program. The model was developed to be very general to enable the simulation of variations in the furnace design and, hence, serve as an aid in finalizing the design. The thermal model is described and a user's guide given. Some preliminary results obtained in testing the model are also given
