Design and Optimization of Cross-corrugated Triangular Ducts Towards Reducing CO2 Emission and Improving Energy Efficiency

Aerosol and Air Quality Research, 2021
Reducing CO2 emission can effectively control global warming. And energy conservation is the most scientifical and systematical ways to reduce CO2 emissions. The total heat exchangers with membrane core, which consist of cross-corrugated triangular ducts

Constructal Optimizations of Liquid-Cooled Channels with Triangle or Square Sections in a Cylindrical Heating Body

Mathematics, 2023
Two new integrated models with heat source–heat sink are established, in which isothermal liquid cooling channels with triangle or square sections are, respectively, embedded in a cylindrical heating body with uniform heat production.

Effect of corrugation profile on the thermal–hydraulic performance of corrugated channels using CuO–water nanofluid

Case Studies in Thermal Engineering, 2014
In this article, laminar flow and heat transfer characteristics of CuO–water nanofluid in straight and corrugated channels are numerically investigated over the Reynolds number and nanoparticles volume fraction ranges of 100–800 and 0–0.05, respectively.

Innovative catalytic streamlined carriers with triangular channels

Chemical and Process Engineering: New Frontiers, 2023
The paper presents research on a novel catalytic carrier, called "streamlined structure". The carrier is a short-channel monolith, whose walls are shaped like an airfoil profile (airplane wing). The intention is heat transfer intensification coupled with moderate flow resistance.

2-D radiation field in photocatalytic channels of square, rectangular, equilateral triangular and isosceles triangular sections

, 2006
In this paper, a Monte Carlo model is used to predict the light intensity profile inside a photocatalytic monolith reactor where the internal walls of the reactor are coated with a light-absorbing and light-reflecting catalytically active film.

Numerical modeling of laminar free overfall in triangular channels

Ain Shams Engineering Journal
Design of open channel transport and flow measurement systems for highly viscous liquids requires accurate modelling of laminar free overfall. In this study, a computational fluid dynamics model was developed to investigate subcritical laminar free ...

Mathematical model of speech signal leakage channels during discrete-quantified conversion

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2020
The purpose of the article is to estimate the leakage channel of a discrete-quantized speech signal with amplitude-pulse modulation. Discrete-quantized analog-to-digital conversion of signals in the article is considered by the example of pulse-amplitude

Prediction of Heat Transfer during Condensation in Non-Circular Channels

Inventions, 2019
It is desirable to know whether correlations for condensation in round tubes can be used for non-circular channels. To investigate this matter, a number of well-known correlations for mini and macro channels as well as some for flattened channels were ...
