This status report details activities during the months of June and July 1996. Work continues on the development of an improved wrap- around heat exchanger/tank model. The focus of the effort during June and July has been on evaluating various `local` methods of evaluating the natural convection boundary layer for use in a two layer model of the natural convection in the tank. The advantage of a local method is that the solution of the boundary layer equations depends on one or more parameters, but not on the upstream solutions. As a result, the solutions of the boundary layer equations can be calculated in advance and tabulated for use in the tank model
