Due to the undesirable environmental consequences ofR12, there is a great challenge to find a suitable substitute for Rl2. A new refrigerant blend Rl34a!R218/R600a (88'Yoi9'Yol 3%) called JSCEON 49 has been developed as a long term, zero ozone depletion-potential replacement for Rl2. A computer program was written to calculate the cycle characteristics, such as cooling capacity, coefficient of ...

A key issue with Hybrid Electric (HEV) and Plug-in Hybrid Electric Vehicles (PHEV) is the cost of these products relative to traditional vehicles. Currently in most cases, the fuel savings do not offset the initial capital expenditure associated with a hybrid. Therefore, an important goal is the cost reduction of these products in order to allow consumers to justify the purchase of these vehicl...

The goal of the present research is to achieve a basic understanding of corrosion of steels by Lead Bismuth Eutectic (LBE). Liquid LBE is under consideration in the transmuter as both a coolant and a target material. There have been studies of LBE, especially by the Russians, but a fundamental understanding and verification of its role in the corrosion of steels is still very

Two-dimensional simulations of transpiration cooling in a laminar, hypersonic boundary layer were performed using the thermochemical implicit nonequilibrium algorithm (TINA): Navier–Stokes solver. Coolant concentration and heat flux results are compared to data obtained from laminar experiments conducted Oxford High Density Tunnel employing flat-plate geometry at Mach 7. TINA successfully predi...

For the validation of Computational Fluid Dynamics (CFD) codes experimental data on fluid flow parameters with high resolution in time and space are needed. ROCOM (Rossendorf Coolant Mixing Model) is a test facility for the investigation of coolant mixing in the primary circuit of pressurized water reactors. This facility describes the primary circuit of a German KONVOI type reactor. All import...
