A numerical study was performed on a plate fi n and oval tube heat exchanger with diff erent kinds of longitudinal vortex generators (LVG). The infl uence of LVG on heat transfer and pressure drop is investigated, and ...

The swirl flow minichannel heat sink has shown to be a promising alternative for thermal management of high heat flux applications, such as electronics and concentrated photovoltaics. Effective heat transfer enhancement ...

One promising way to enhance the heat transfer coefficient (HTC) and the critical heat flux (CHF) is modifying the heating surface morphology by using machining techniques, coating, and chemical processes. Microstructured ...

A two dimensional numerical investigation of the unsteady laminar flow pattern and forced convective heat transfer in a channel with a built-in rectangular cylinder is presented. The channel in the entrance region has a ...

This study presents experimental results for the heat transfer coefficient during pool boiling of DI water and Al2O3-water based nanofluid at saturation conditions. Based on these data, an analysis of the heat transfer ...

The population growth and industrial development increase the demand for energy and the solar energy conversion is an important alternative to complement the world energy matrix. Flat plate solar collectors are devices ...

The solar energy is a renewable source that has a great potential for conversion into thermal energy or for generation of electric power through photovoltaic panels in Brazil. Concerns about environmental impacts and the ...
