The purpose of this particular report describes the validation of heat conduction analytical model which comprises part of the subway environment simulation (SES) computer program. The conduction model is a closed form transfer cylindrical coordinate frame solution which treats the case of unsteady heat transfer in two, interfacing concentric materials. The validation was accomplished through field tests conducted within the Toronto Transit Commission subway over several months. The field measurements, including temperature at the tunnel air-wall interface and temperature in the earth beyond the tunnel structure, were compared directly with analytical model predictions.
