Consider an NHL regulation hockey puck 3 inches in diameter and 1 inch thick (7.62 cm by 2.54 cm). Determine the surface temperature of the top of the puck after an 83 MPH (37 m/s) slapshot from center ice by Paval Datsyuk. The ice temperature is -4°C and the temperature of the air in the Joe Louis Arena at ice level is kept at 17°C. The heat transfer may be assumed to be steady state and one-dimensional through the puck between the ice and the air (k= 0.2 W/mK for the Vulcanized rubber puck). A thin water film develops during the slapshot that is 3.5 mm thick between the puck and the ice. This water film is considered a bounded flow between the puck and the ice.
