Abstract : A mathematical heat transfer model developed in ANSYS, a commercial finite element analysis program, is used to improve the thermal performance of the Self-Heating Individual Meal Module (SHIMM). Design parameters such as size and arrangement of the Flameless Ration Heater (FRH) and container materials are optimized with the Finite Element Analysis (FEA) model. Evaluation factors include heating rate and uniformity during the self-heating process. Results from the analysis showed that the use of two one-third-size heaters with a different tub materials is the most thermal efficient SHIMM. An alternative design concept for the SHIMM is also discussed.
