Forced convection from a finitelength wedge in laminar flow
Abstract
Forced convection heat transfer for air flow over a wedge with a finite length in the flow direction was experimentally investigated. The average heat transfer coefficient versus approach velocity followed the same trend as the FalknerSkan wedge flow but was about 28 percent higher. The measured freestream velocity deviated significantly from FalknerSkan wedge flow, especially near the trailing edge. Measured freestream velocities were used to predict the local heat transfer coefficients by the method of Smith and Spalding (1958). This method was found to underpredict heat transfer coefficients because it is based on FalknerSkan wedge flow, which applies only to an infinite wedge. Heat transfer measurements were also made on an extended wedge with only the front half heated. The measured heat transfer coefficient were closer to the infinite wedge results, but were still slightly higher.
