Uniform Wall Heat Flux

An experimental technique for obtaining a uniform wall heat flux has been used to determine the local heat transfer coefficients around a cylinder. Data are presented for a single cylinder, for cylinders in tandem, and cylinders located in the entrance of a tube bank. Results are compared to those of other studies with uniform wall heat flux. For the single cylinder, these are found to depend upon blockage, aspect ratio, and free-stream turbulence. For both inline and staggered tube arrangements, the heat transfer coefficient distribution depends on row location but appears to be nearly established by the third row.
