This work explores the turbulent thermal-hydraulic performance in circular heat exchanger
tubes with multiple rectangular winglet vortex generators. Numerical simulations …

Twisted elliptical tube heat exchangers are promising in terms of improving the heat transfer
efficiency on the tube side, decreasing the pressure drop on the shell side, and reducing the …

An experimental investigation on the aerothermal performance of a heat exchanger tube
equipped with newly designed broken V-ribbed twisted tapes (B-VRT), was carried out. In …

Nearly half of the insident solar radiation to the photovoltaic (PV) units will be converted to
heat, which leads to a high operating temperature, cell structural damage, and the lifetime …

In this paper, the experimental effect of the continuous and discontinuous twisted tapes
turbulator (perforated and non-perforated) on the inner side of the internal tube in the double …

It is generally recognized that the heat transfer rate can be improved using active, passive
and compound methods. The use of twisted tape inserts in a pipe flow is one of the passive …

At present study, thermal performance of a double tube heat exchanger due to stream of
air/water two phase flow through inner tube is experimentally studied. Air and hot water were …

Rectangular winglet vortex generators (RWVGs) are put forward to intensify turbulent heat
transfer in circular tubes. Two configurations of RWVGs, including parallel type (P-RWVGs) …
