Prediction of Energy Concentration during Microwave Heating with a Thermal Diffusion Dimensionless Number
In a previous study, the correlation equation with a dimensionless number (As) of local microwave heating was proposed to solve the problem of a wider temperature distribution caused by heat generation within penetration depth during microwave heating. However, the previous model did not account for...

| Summary: | In a previous study, the correlation equation with a dimensionless number (As) of local microwave heating was proposed to solve the problem of a wider temperature distribution caused by heat generation within penetration depth during microwave heating. However, the previous model did not account for thermal diffusion. Consequently, a new model, including the Prandtl number, was developed. A boiling experiment for the solution with different Prandtl numbers was carried out during microwave heating, and our old model was developed as an expression that includes the Prandtl number. From the consistent parameter fitting, the developed model will be useful for achieving homogeneous temperature distribution during microwave heating. |
