This study investigates the turbulent entropy production rate of ferrosoferric oxide/water (Fe
3 O 4/H 2 O) nanofluid flowing through outward corrugated pipes of different profiles …

The economic and operational constraints are the most important ones when it comes to
decide to use any performance enhancement method. In this paper, the effect of Al 2 O 3 …

Innovative designs of heat exchangers are crucial to increase the heat transfer effectiveness
for the purpose of compactness, energy savings, and emission reductions, among others. In …

This paper examines the turbulent hydrothermal performance of boehmite/water–ethylene
glycol (γ-AlO (OH)/H 2 O-EG) nanofluid flowing through a square duct fitted with various …

The ever-growing interest in developing compact and more effective heat exchangers
necessitates the investigation of combined passive solutions. Despite the diverse related …

Improvements in heat transfer technologies are a key factor in making all industries that use
