Solar Bubble Dryer Preliminary Simulation Studies

Among the renewable energy, solar bubble dryer is cost-effective drying technologies for rural India. Solar bubble dryers’ technical and scientific study for Indian conditions with respect to this simulation studies was performed. To dry agricultural produce in this technology, we are using solar PV panel to blow the air thus making complete renewable energy based and to reduce environmental concerns associated with post-harvesting technologies. Solar bubble dryer 3D environmental study results indicated 340–360 K (6 h, 9 AM–5 PM). There were two stagnation areas at the inlet section, and further, it has increased the temperature in these zones up to 380 K in the mid of the day 1 PM–3 PM. As the studies were preliminary, one only concentrated on steady-state analysis. Air sufficiently alleviated to dry agricultural produce in solar bubble dryer. Further, it can be extended to time-dependent study.
