Investigation on the Effect of Length and Amplitude of Sinusoidal Wavy Vortex Generators on the Heat Transfer Rate, Pressure Drop, and London Factor in Compact Heat Exchangers

Autor: Davood Barati, Mohammad Nimafar, Gholamreza Salehi

Publikováno v: Journal of Mechanical Materials and Mechanics Research. 6:1-13

Compact heat exchangers (CHE) improve the heat transfer rate with lighter weight and lower volume than other counterparts. An important point in CHEs is their higher pressure drop relative to conventional heat exchangers. This study aims to investiga

Numerical investigation on heat transfer enhancement inside a rectangular microchannel with vortex generator using TiO2, Cuo-water nanofluids

Autor: Arash Behaeen, Mohammad Nimafar

Publikováno v: Journal of Mechanical Engineering Research. 3

One of the innovative ways to improve heat transfer properties of heat exchangers, is using nanofluids instead of traditional fluids. Due to presence of metal and oxides of metal particles in nanofluids structure, they have better potential in differ

Experimental Investigation of Split and Recombination Micromixer in Confront with Basic T- and O- type Micromixers

Autor: Vladimir Viktorov, Mohammad Nimafar, Matteo Martinelli

The paper presents an experimental comparison of three types of static micromixer. Efficiencies of a split and recombination micromixer (SAR) based on plate symmetrical modules (PSM) and basic T-type and O-type mixers are examined. Experimental tests

Experimental comparative mixing performance of passive micromixers with H-shaped sub-channels

Autor: Vladimir Viktorov, Matteo Martinelli, Mohammad Nimafar

This paper presents a new type of passive microfluidic mixer called the “H-micromixer”. This type of passive micromixer is based on the splitting and recombination (SAR) process, meaning that the two fluids to be mixed are split and recombined to

A novel generation of 3D SAR-based passive micromixer: efficient mixing and low pressure drop at a low Reynolds number

Autor: Vladimir Viktorov, Mohammad Nimafar

Publikováno v: Journal of Micromechanics and Microengineering. 23:055023

This study introduces a novel generation of 3D splitting and recombination (SAR) passive micromixer with microstructures placed on the top and bottom floors of microchannels called a ?chain mixer?. Both experimental verification and numerical analysi
