Visualization of Thermo-Hydrodynamic Behavior in Flat hydrodynamic transfer pipes a270

Jan 29, 2021 · In this paper, the visualization of the thermo-hydrodynamic behavior in flat-plate pulsating heat pipe (FP-PHP) with HFE-347 is experimentally investigated. The FP-PHP is vertically placed with filling rate of 20% to 70% and heating power of 20 W to 140 W. A high-speed camera is used to record the two-phase flow in the FP-PHP.

Transient thermal and hydrodynamic model of flat heat pipe hydrodynamic transfer pipes a270

Dec 01, 2008 · In order for the heat pipe to operate properly, it is absolutely necessary for the maximum capillary pressure head (P c,max) developed by the wick structure to be greater than the capillary pressure P c. This condition defines the maximum heat transfer capability of the FHP, expressed as P c,max > P c. If this pressure balance is not satisfied, the FHP performances break down, and the heat transfer limitation, usually called the capillary or hydrodynamic Predicting and Preventing Flow Accelerated Corrosion in hydrodynamic transfer pipes a270Flow accelerated corrosion (FAC) of carbon steels in water has been a concern in nuclear power production for over 40 years. Many theoretical models or empirical approaches have been developed to predict the possible occurrence, position, and rate of FAC. There are a number of parameters, which need to be incorporated into any model. Firstly there is a measure defining the hydrodynamic severity of the flow; this is usually the mass transfer rate. The development of roughness due to FAC and its effecSee more on hindawi hydrodynamic transfer pipes a270Some results are removed in response to a notice of local law requirement.

Although there are numerous experimental investigations on the ice-water two-phase flow, theoretical studies are very rare which characterizes flow behaviour due to

Numerical study on maximizing heat transfer and minimizing hydrodynamic transfer pipes a270

Jan 01, 2021 · The total heat transfer in porous media is supplemented by interfacial heat transfer i.e., the heat transfer that takes place by the fluid from the foam structures of the porous media. As modeled through LTNE heat transfer model, it can be observed that total heat transfer in the porous media can be distinctly analyzed in two ways.Modeling Loss-of-Flow Accidents and Their Impact on hydrodynamic transfer pipes a270Long-term high payload missions necessitate the need for nuclear space propulsion. The National Aeronautics and Space Administration (NASA) investigated several reactor designs from 1959 to 1973 in order to develop the Nuclear Engine for Rocket Vehicle Application (NERVA). Study of planned/unplanned transients on nuclear thermal rockets is important due to the need for long-term Laminar flow in rotating curved pipes | Journal of Fluid hydrodynamic transfer pipes a270Apr 26, 2006 · When a curved pipe rotates about the centre of curvature, the fluid flowing in it is subjected to both Coriolis and centrifugal forces. Based on the analogy between laminar flows in stationary curved pipes and in orthogonally rotating pipes, the flow characteristics of fully developed laminar flow in rotating curved pipes are made clear and definite by similarity arguments,
