I am testing the effects of the injecting fluid temperature on fault stability with a 2D THM model in OGS. But I am not sure how to give a reasonable heat source term in the prj?
For example, I want to inject cold water into a geothermal reservoir:
cold water temperature: 30℃ (303.15K)
geothermal reservoir temperature: 150℃ (423.15K)
injection rate: 1e-6 kg*m^(-2)*s^(-1)
Could anybody tell me how I can set this heat source term?
