Abstract :An analytical equation for uniform, normal surface microwave power for cylindrical objects has been proposed. The surface microwave power for cylindrical objects undergoing unidirectional energy transfer was a function of average power absorbed, dimensions of the cylinder and the attenuation constant. A finite difference model has been developed to predict the temperature profiles. The numerical model has been tested against well-known analytical solutions and excellent agreement was observed. This model has been used to simulate literature temperature profiles. Satisfactory agreements were obtained for the interior points. However, the predicted surface temperatures were higher than the experimental temperatures. It is believed that the proposed expression for the surface power may be used to check the uniformity and normalcy of the surface microwaveKeywords : microwave, modeling, food, temperature
