To have a high air speed into the chimney we must have to increase the gap between the temperature of the air in and out the device... So, adding geothermel energy (60°C) can with solar irradiance increase this gap and hence...!!!
The average specific heat of the air is 1.007 kJ/kg K and to heat the air from say 20 oC to 100oC, you need to add 80 kJ/kg of air . Then you should calculate the amount of heat available by the geothermal energy and the solar energy and make an energy balance. Good luck
Hello Mr Udaya Rahubadda
Thak you very much.
Hello Mr Mohamed .S and Thank you
Our air flow within chimney is around (0.2 m3/s i.e.0.26 kg/s at 45°C) ; so it is not possible to reach 100°C of air temperature using geothermal water at liquide state...
This will be possible only with using an over heated water vapour (i.e T>>100°C).
Regards.
