چکیده

Thermal diffusivity is a physical quantity that is represented by the thermal properties of the soil amid changing known conditions such as global warming which humanity is facing. The heat transfer and temperature change in the surface layers of the soil at a depth of 2 m were studied in the sandy mixture soil in Najaf and according to the location using the vertical heat exchanger. The best thermal diffusivity was recorded at a temperature of 40 degrees Celsius and at a flow of 0.5 liters per minute for one day, ranging from 0.00118682 to 0.00118672. And the best thermal performance coefficient was at a temperature of 50 degrees Celsius and a flow of 1 liter per minute.
