Concept of CFD model of natural draft wet-cooling tower flow

EPJ Web of Conferences, 2014
The article deals with the development of CFD model of natural draft wet-cooling tower flow. The physical phenomena taking place within a natural draft wet cooling tower are described by the system of conservation law equations along with additional ...

Reverse Electrodialysis: Co- and Counterflow Optimization of Multistage Configurations for Maximum Energy Efficiency

Membranes, 2020
Reverse electrodialysis (RED) is one of the techniques able to harvest energy from the salinity gradient between different salt solutions. There is a tradeoff between efficiency and generated power in a RED stack. This paper focuses on efficiency.

Outflows and Massive Stars in the protocluster IRAS 05358+3543

, 2013
We present new near-IR H2, CO J=2-1, and CO J = 3-2 observations to study outflows in the massive star forming region IRAS 05358+3543. The Canada-France-Hawaii Telescope H2 images and James Clerk Maxwell Telescope CO data cubes of the IRAS 05358 region ...

Numerical study on the influence of flow direction and fluid type on heat transfer and pressure drop in a two-tube spiral heat exchanger with innovative conical turbulators

Case Studies in Thermal Engineering
In this research, numerical analysis will be conducted on the thermal and hydraulic performance of a spiral two-tube heat exchanger. The study employs an innovative turbulator design with curved outer blades and a semi-conical section with two openings ...

Experiments on the twisted vortex state in superfluid 3He-B

, 2007
We have performed measurements and numerical simulations on a bundle of vortex lines which is expanding along a rotating column of initially vortex-free 3He-B.

Concentration in Renal Counterflow Systems

Biophysical Journal, 1966
In this paper earlier work on two-loop counterflow systems is extended to n-loop systems. It is shown that a large class of such systems in which exchange between the flow tubes is passive is unable to concentrate or dilute.

Thermal calculation of heat exchangers with simplified consideration of axial wall heat conduction

E3S Web of Conferences, 2018
The usual thermal design and rating methods [1, 2] for heat exchangers neglect axial wall heat conduction in the separating walls and external shells of recuperators and in the solid matrix of regenerators. This may lead to undesirable undersizing.

Sample dispersion in isotachophoresis with Poiseuille counterflow

, 2013
A particular mode of isotachophoresis (ITP) employs a pressure-driven flow opposite to the sample electromigration direction in order to anchor a sample zone at a specific position along a channel or capillary.

Analysis of Heat Transfers inside Counterflow Plate Heat Exchanger Augmented by an Auxiliary Fluid Flow

The Scientific World Journal, 2014
Enhancement of heat transfers in counterflow plate heat exchanger due to presence of an intermediate auxiliary fluid flow is investigated. The intermediate auxiliary channel is supported by transverse conducting pins.
