Computation of airflow effects on heat and mass transfer in a microwave oven

摘要: Abstract The magnitude of surface heat and mass transfer coefficients in microwave ovens is important to control food temperature moisture are a result the faint airflow present oven cavity radiation. Magnitude patterns inside resulting were studied using computational fluid dynamics model process. governing Navier–Stokes energy equations solved for both natural, forced combined convection. distribution on computed 3-D with one inlet outlet cylindrical placed oven. Calculated convective coefficient values found be same range as has been used literature. A convection regime proves beneficial uniformity reduction accumulation Radiation exchange between interior calculated shown order coefficients.
