An Experimental and an Analytical Study of the Flow Field and Heat Transfer of a Jet Stirred Bath

摘要

The flow field and heat transfer characteristics of a jet-stirred bath are studied using a flow visualization technique and a finite-difference numerical calculation computer code. A description of water model used in the study is given. The data collection and data reduction phases of the flow visualization method are explained. A description of the TEACH-T computer code for the solution of recirculating turbulent flows (elliptic partial differential equations) is provided along with a discussion on the present state of mathematical turbulence modeling. Predictions of the variation of the film coefficient along the wall of the bath using both methods are given for jet Reynolds numbers of 43,733 and 30,261. Although the flow visualization technique did not give accurate quantitative data, its utility in qualitative studies is acknowledged. The TEACH-T computer code gave predictions correct to at least an order of magnitude.
