Multigrid Scheme for Thermohydraulic Flow

Numerical Heat Transfer, Part B: Fundamentals, 1984
An efficient scheme has been developed for the numerical solution of the Navier-Stokes and energy equations applied to the flow of an incompressible fluid in a two-dimensional channel. A vorticity-stream function formulation with a generalized curvilinear coordinate system is used for a wide range of geometric configurations.

Thermohydraulic test on bentonite

Journal of Thermal Analysis and Calorimetry, 2006
Swelling clays like bentonite are proposed as a buffer in high level nuclear waste repositories. An experimental device useful for thermo-hydraulic analysis of the samples behavior is outlined from room temperature to 373 K. The temperature distribution is established by axial heating of cylindrical samples.

Nonstationary thermohydraulic code – UNSCELM

Atomic Energy, 2012
The UNSCELM code was developed to perform nonstationary thermohydraulic fuel-assembly calculations over cells cooled by a single-phase coolant. In contrast to previously developed codes, the assumption that the pressure is constant in a transverse section of a fuel assembly is not used in this code. This makes it possible to take account of large local

Physics of thermohydraulic explosions

Physical Review E, 1998
We propose a phenomenological model for explosive water-melt interactions. Thermohydraulic fracturing was experimentally identified to be the main contributor to explosive energy release. We found experimental evidence that the model is applicable for a variety of melt compositions with very different thermal and rheological properties.

Analysis of thermohydraulic explosion energetics

Journal of Applied Physics, 2005
Thermohydraulic explosion, caused by direct contact of hot liquids with cold water, represent a major danger of volcanism and in technical processes. Based on experimental observations and nonequilibrium thermodynamics we propose a model of heat transfer from the hot liquid to the water during the thermohydraulic fragmentation process.

Thermohydraulics Oscillations and Numerical Integration

Nuclear Science and Engineering, 2002
There is currently much interest in developing new codes and improving the existing ones to be able to predict instabilities of nuclear power reactors. Stability calculations are very sensitive to the models used for the reactor and the numerical methods used to integrate them.

Data library on thermohydraulic processes

Soviet Atomic Energy, 1987
The results of work on the creation and development of the ASSPD system, and the LITPD library as a fundamental part of the system, should promote the enhancement of the efficiency and reliability of designed nuclear power plants and research on thermohydraulics.

Boiling and Thermohydraulics Within Pressure Vessels

2020
Exposure of pressure vessels to fire can result in catastrophic explosion and escalation of accidents. The safe transportation of cargo in pressure vessels therefore requires knowledge of what will happen to the cargo in the event of a vehicle derailment or rollover resulting in fire exposure.

Scaling of thermohydraulic systems

Nuclear Engineering and Design, 1996
Abstract The importance of scaling is demonstrated for experiments in small-size test facilities which are used to simulate the thermohydraulic system response of full-size industrial plants. It is shown how scaling facilitates (1) the quantitative ranking of thermohydraulic processes in their order of priority, (2) the rational selection of a test ...
