The cross-flow heat exchanger is a special type of heat exchanger involving the exchange of
heat in the case of two fluids flowing in an orthogonal direction. The heat exchanger often …

The present article concerns with thermohydraulic performance, flow friction and entropy
generation analysis in a heated tube contained with louvered winglet tape (LWT). The …

The cross‐flow heat exchanger involves a tractor moving between two fluids that flow in a
direction perpendicular to each other, and one of the fluids is often a liquid and the other is a …

The article is concerned with investigating the effect of insertion of louvered V-winglet (LVW)
vortex generators on convection heat transfer and pressure loss in a tubular heat exchanger …

This article proposed a new arrangement of planar vortex generators (VGs) and punched
VGs within a heated tube. The airflow and heat removal performance of the VGs with new …

An efficient technique for reducing frictional loss by punching holes on the surface of vortex
generators has been extensively researched, particularly in the form of louver-punched …

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) …

Novel self-join winglet vortex generators (SWVGs) consisting of multiple pairs of connected
V-shaped rectangular winglets were put forward for enhanced heat transfer of turbulent …

A numerical investigation was conducted to explore the heat transfer optimization effect of
circular tube heat exchanger with L-shaped twisted tape insert and to find the optimal …

A punched delta winglet (PDW) was proposed and investigated numerically and
experimentally in a turbulent flow. The effect of delta winglets with different punching holes …
