Abstract
A combined experimental and theoretical simulation approach was developed to evaluate performances of a surface cooling pad in reducing temperatures in human knee tissue. Experiments were performed on healthy volunteers to collect skin temperature values under a cooling pad during cooling sessions of 20 minutes. Then a whole-body heat transfer model was developed to extract the unknown overall heat transfer coefficient. Parametric studies were conducted to investigate the effects of the coolant temperature and overall heat transfer coefficient on the tissue temperature field. The simulation results demonstrated the effectiveness of the cooling pad in reducing temperatures by at least 2�C (37�C to 35�C) within a tissue region less than 34 mm under the cooling pad. This was achieved with a coolant temperature of 0�C for a cooling duration of 20 minutes. Results of this study would provide information to clinicians on whether to prescribe cooling therapy to patients after surgery.
