Saturation Conditions in Elongated Single-Cavity Boiling Water Targets
نویسندگان
چکیده
It is shown that a very simple model reproduces the pressure versus beam current characteristics of elongated single-cavity boiling water targets for F production surprisingly well. By fitting the model calculations to measured data, values for a single free parameter, namely an overall heattransfer coefficient, have been extracted for several IBA Nirta H2 O targets. IBA recently released details on their new Nirta targets that have a conical shape, which constitutes an improvement over the original design that has a cylindrical shape [1,2]. These shapes are shown schematically in Figure 1.

Simulation of Boiling Heat Transfer within Water Jacket of 4-cylinder Gasoline Engine (TECHNICAL NOTE)
Shrinking the engine has been a great interest for many years. Providing more amount of heat transfer may supply possibilities for size reduction in engine parts specifically the engine water jacket that is of concentration for the present study. Boiling phenomenon, by providing more amounts of heat transfer in comparison with single-phase, provides conditions for size reduction. In this paper ...

In this paper, a modified two-fluid model has been adopted to simulate the process of upward vertical subcooled flow boiling of refrigerant R-113 in a vertical annular channel at low pressure. The modified model considers temperature dependent properties and saturation temperature variation and was validated against a number of published low-pressure subcooled boiling experiments. The results s...

متن کاملInvestigation of Applicability of Using Water Mist for Cooling High-Pressure Turbine Components via Rotor Cavity Feed Channels
Mist cooling has been considered as a potential means to significantly enhance cooling the hot components of a gas turbine. However, it is a great challenge to transport mist to locations where cooling is needed due to the high temperature environment and rotating components in the gas turbines. One plausible way is to transport high-pressure water to the rotor cover-plate cavity via a feed cha...
