• The effect of the waviness on thermal contact resistance is examined. The experiments performed on a simplified model of waviness show that the thermal contact resistance is roughly said to be the sum of the resistances for roughness and waviness in series. Long before investigating the theoretical analyses shown in the previous reports, we have obtained experimentally a practical method of estimating the thermal contact resistance. That is, on the assumption that the thermal contact resistance is the resultant of resistances to metalmetal and metal-medium-metal parallel heat flows and the additional resistance attached in series to the metal-metal heat flow, this additional resistance may be taken to be constant for each metal. This fact will be verified theoretically.
