Abstract: This study aims to determine the effect of the aspect ratio of the cross section of a rectangular twisted tape on the laminar heat transfer characteristics inside an isothermally heated circular pipe. Detailed three-dimensional ...

Abstract: In this article, the effect of butanol/diesel and pentanol/diesel blended fuel with different proportions on the energetic, combustion, and emissions parameters of a diesel engine was studied. First, an engine model was ...

Abstract: A single-stage vapor compression refrigeration system becomes inefficient and impractical when the temperature lift between the evaporator and the condenser becomes large. Under the high-temperature lift, different losses ...

Abstract: In this study, an attempt has been made to carry out a numerical investigation using water-based Al2O3 nanofluid, flowing through a circular tube under constant inlet temperature and constant heat flux conditions in the ...

Abstract: An attempt has been made to investigate numerically a two-stage refrigeration system with flash intercooler of 50 kW cooling capacity using refrigerant R410A and its possible alternative R32. Development of the simulation ...
