The study of heat transfer coefficient of supercritical water plays an important role in improving the heat transfer efficiency of the reactor. Taking the supercritical natural circulation experimental bench as the research object, the effects of power, flow, pipe diameter and mainstream temperature on...
2). In a previous experiment in which water was condensed on a LIS performed by Xiao et al., the condensation heat transfer coefficient was measured experimentally and reported to be 100% greater than that of dropwise condensation on a flat surface; however, the heat transfer coefficients ...
The bubble diameter chiefly depends on the interfacial tension between vapor and oil, and it can be assumed almost constant; however, bubble velocity increases in a higher rate of water loss, resulting in a higher Reynolds number and heat transfer coefficient as well (van Koerten et al., 2017...
Determination of Heat Transfer Coefficient for Air-Atomized Water Spray Cooling and Its Application in Modeling of Thermomechanical Controlled Processing o... The paper presents the method and results of determination of heat transfer coefficient for air-atomized water spray cooling with consideration of...
It is a process value of the heat transfer in between a fluid and a body. For example from cooling water to the steel of a heat exchanger. The heat transfer coefficient depends only on the fluid, its movement and the surface of the solid body. However, not from the material of the so...
This article presents an application of inverse algorithm for reconstruction of heat transfer coefficient (HTC) for a water jet impinging a flat surface. Such an approach, allows for decoupling complex fluid flow from heat conduction in a solid impinged by jet. The approach starts with ...
How to get the value of convection coefficient [h] from Fluent directly ? Thank you, May 20, 2013, 20:57 I also need help for that. #12 elina Member Elina Mathew Join Date: Mar 2013 Posts: 47 Rep Power: 13 Hi I am using a heat transfer problem where there is hot water fl...
The design of steam and hot water injection projects requires estimation of casing temperatures and wellbore heat losses. Several authors have shown that well bore heat losses and casing temperatures can be calculated if the overall heat transfer coefficient is known. A brief derivation is presented ...
The corresponding dimensional mass transfer coefficient between the ASL and the lumen is thus\(k_i = \text {Sh}_i {\mathscr {D}}/R_i\). If Sh\(_{i}\)is assumed independent of the axial coordinate (the validity of this assumption is discussed in Haut et al.28), Eqs. (4and6) ...
