Analysis of Relaxation Time of Temperature in Thermal Response Test for Design of Borehole Size

Analysis of Relaxation Time of Temperature in Thermal Response Test for Design of Borehole Size

A new practical method for thermal response test (TRT) is proposed herein to estimate the groundwater velocity and effective thermal conductivity of geological zones. The relaxation time of temperature (RTT) is applied to determine the depths of the zones. The RTT is the moment when the temperature...
