Experimental mixedconvection heat transfer from a large, vertical surface in a horizontal flow
Abstract
The convective heat transfer from and the boundary layer flow on a vertical, 3msquare surface parallel to a horizontal air flow were studied. The test conditions ranged from pure forced convection driven by a horizontal inertial force induced by the horizontal freestream flow, to combined forced and free convection (i.e., mixed convection) driven by orthogonal forces, the horizontal inertial force and a vertical buoyant force generated by the heated vertical wall, to pure free convection driven by the vertical buoyant force. The emphasis was on mixed convection. Surface temperatures and freestream velocities ranged from 40 to 600 C and 0 to 6.0 m/s, respectively, resulting in Reynolds numbers (Re) and Grashof numbers (Gr) up to 2 x 10(6) and 2 x 10(12), respectively. Convective heattransfer and boundarylayer profiles of mean velocity, flow angle, and temperature were measured. The heattransfer results showed the range of conditions for which the heat transfer was characterized either as forced, mixed, or free convection.
