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 ...

A critical review of the available information about heat transfer between a packed bed with cocurrent downflow of gas and liquid and an external medium is undertaken. Several aspects as experimental set-ups and methods ...

An experimental apparatus and a computational routine were developed and implemented in order to obtain the sessile drop images and the contact angle measurement for different fluids and surface conditions. Moreover, ...

The aim of this study is to investigate the influences of different parameters on the boiling phenomenon. In this paper, a new correlation to predict the pool boiling heat transfer coefficient is presented. The developed ...

The evolution of the processes for modifying/manufacturing surfaces has facilitated the advancement in pool boiling research with surfaces capable of increasing the heat transfer coefficient (HTC) and the critical heat ...

This paper presents new experimental flow boiling heat transfer results in micro-scale tubes. The experimental data were obtained in a horizontal 2.3 mm I.D stainless steel tube with heating length of 464 mm, R134a 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 ...

Despite its importance for designing evaporators and condensers, a review of the literature shows that heat transfer data during phase change of carbon dioxide is very limited, mainly for microchannel flows. In order to ...
