Enhanced heat transfer in a solar air heater with double-flow configuration by electrohydrodynamic technique

Thermal characteristics of laminar forced convection inside solar flat-plate air heaters with double-flow configuration using the electrohydrodynamic technique are examined numerically. The electric field is generated by the wire electrodes with different arrangements charged with DC high voltage ra...
