Thermohydraulic Simulation of Heat Exchanger Networks

Industrial & Engineering Chemistry Research, 2010
This paper presents a simulation scheme of heat exchanger networks considering thermal and hydraulic effects simultaneously. The determination of network temperatures is carried out together with the evaluation of flow rates and pressures along the network, considering head losses in heat exchangers and associated piping.

Thermohydraulic effects of safety relief valves

Experimental Thermal and Fluid Science, 1999
Abstract An experimental study of the thermohydraulic performance of the safety relief valve (SRV) is presented. The study showed that the single and two-phase conditions upstream the SRV cause significant changes in the flow through the SRV. Five SRVs were tested covering a pressure range of (4.5–75) bar.

Thermohydraulic modeling of pulsed laser welding

ICALEO 2013: 32nd International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2013
The major aim of this study is to increase our understanding of the link between operating parameters and thermo-hydraulic evolution in the welding area, in the case of an isolated impact made with a Nd:YAG pulsed laser on a thin Ti6Al4V sheet. Two numerical approaches are used to model both the interaction stage and the cooling one.

Fundamentals of liquid metal boiling thermohydraulics

Nuclear Engineering and Design, 1984
Abstract Developments in space and in nuclear-energy have demonstrated the heat-transfer utility of liquid metals in both low-pressure and high-temperature applications. Compared with water or organic liquids, liquid metals are advantageous in the design of thermal features, as for heat transport at high-temperatures at normal pressures.

Fractional step methods for thermohydraulic calculation

Journal of Computational Physics, 1981
Abstract A method of fractional steps is used to extend a semi-implicit finite-difference technique for multidimensional two-phase flow calculations. This extension permits time step size to be chosen independent of convection velocities in one space direction, and still resolves multidimensional coupled sonic and phase exchange effects implicitly by

Thermohydraulic characteristics of refrigerator-radiator devices

Journal of engineering physics, 1981
Generalized relations are derived for determining the thermal efficiency and the outlet temperature of tubes in radiative heat exchangers with a nonuniform distribution of heat carrier between these tubes.

Transient Thermohydraulic Modeling of Capillary Pumped Loop

SAE Technical Paper Series, 2011
<div class="section abstract"><div class="htmlview paragraph">“More electric” aircraft requires more power electronics integration. Traditional cooling systems reach their maximal performances because of too high thermal dissipation of these components.

Thermohydraulic design of the KSTAR vacuum vessel

Fusion Engineering and Design, 2001
The KSTAR vacuum vessel is designed as a racetrack-shaped double wall configuration with major ports, reinforcing ribs, bellows and a leaf spring style support structure. The vessel will be baked out by hot nitrogen gas and cooled with shielding water during normal operation.

Chemical Thermohydraulics of Steam Generating Systems

Nuclear Technology, 1981
In steam generating systems, the concentration of solutes in contact with heat transfer surfaces, a decisive factor in determining the actual material corrosive environment, exceeds that of the bulk fluid. This paper deals with steam generation on the unobstructed tube surfaces, and the effects of deposition of corrosion products on concentration of ...
