WebJan 1, 2015 · In forced convection, the fluid motion is imposed. In natural convection, the fluid motion is induced by the heat transfer process itself. Mixed convection flows are for those cases where there is a forced velocity, but buoyancy effects are strong enough to influence the flow field as well. WebThe experiment was conducted in three drying modes such as natural, forced convection solar dryer and open sun drying. The hourly data for the rate of moisture removal, sample temperature, relative humidity inside and outside the solar and ambient air temperature for complete drying have been recorded.
