Using a preliminary coolant outlet temperature distribution from early core design analyses, the coolant temperature at the succeeding superheater inlet is predicted. Temperature influences on mixing, as well as on the pressure drop, will be discussed. All analyses have been performed with the CFD ...
Coolant Mixing in the HPLWR Upper Plenum 喜欢 0 阅读量: 16 作者:Alexander,Wank,Thomas,Schulenberg,Andreas,G.,Class 摘要: The High Performance Light Water Reactor (HPLWR) is a new concept of light water reactors, cooled and moderated with water at supercritical pressure conditions of around 25...
At the opposite side the lower borated coolant is entrained by the colder safety injection water and transported to the core. The validation proves that ANSYS CFX is able to simulate appropriately the flow field and mixing effects of coolant with different densities. (authors) 展开 ...

(4) using heat from the second coolant circuit (3) and/or for cooling the air of the motor vehicle interior, in that heat from the second coolant circuit (3) can be fed to the first coolant circuit (2), particularly by means of the circuit heat exchanger (7) or the mixing valve (...
The driving force for removing the heat is the temperature difference between the bulk polymer and the coolant: (1)qc=hTA(TP−Tc) where A is the interior barrel area, hT is the overall heat transfer coefficient which is a measure of the heat removal capacity of the extruder, and Tp ...
Coolant mixing in LMFBR rod bundles and outlet plenum mixing transients. Progress report, December 1, 1975--February 29, 1976 Progress is summarized in the following task areas: assessment of available data, experimental water mixing investigations, analytic model development, and...

Reactor pressure vessel of a water-cooled nuclear reactor installation In such a reactor pressure vessel, gases collect in the upper plenum after depressurisation of the primary coolant system. They are reduced via a pressure tube by purging with an inert gas. In normal operation of the reactor...
It is concluded that LES is a promising tool to accurately analyze the coolant temperature fluctuations associate with high-Reynolds number turbulent mixing flowsHu, L WKazimi, M SHu, L.W., Kazimi, M.S., "Large Eddy Simulation of Water Coolant Thermal Striping in a Mixing Tee Junction,"...
