Forced convection heat transfer of a vertical shrouded fin array
Summary form only given. The detailed local distribution is obtained of the convective heat transfer coefficient on the fin structure. A mass transfer system using the naphthalene sublimation technique is chosen for the study. The test model is fabricated by coating a layer of naphthalene on the fin surface; this gives the surface an equivalence to the isothermal boundary condition in heat transfer. This also implies that the fin array has 100% of fin efficiency. A state-of-the-art, computer-automated measurement system is used to acquire the naphthalene surface profiles before and after the surface exposure to the air stream in a wind tunnel. The present test uses fixed values of fin height-to-space ratio (approximately 1.5) and the streamwise dimension (approximately 5 fin heights).<>
