Convective heat transfer in foams under laminar flow in pipes and tube bundles.

The present study reports experimental data and scaling analysis for forced convection of foams and microfoams in laminar flow in circular and rectangular tubes as well as in tube bundles. Foams and microfoams are pseudoplastic (shear thinning) two-phase fluids consisting of tightly packed bubbles with diameters ranging from tens of microns to a few millimeters. They have found applications in ...

Convective Heat Transfer from a Heated Rotating Disk at Arbitrary Inclination Angle in Laminar Flow

In this paper, experimental data and numerical results of heat transfer from a heated rotating disk in still air are presented over a large range of inclination angles and a dimensionless correlation is developed for forced, natural and mixed convection. The measured Nusselt number over the rotating disk is compared with the numerical results. The goal of the present research is to develop a se...

Experimental investigation on heat transfer and pressure drop of Al2O3-base oil nanofluid in a helically coiled tube and effect of turbulator on the thermal performance of shell and tube heat exchanger

These days With respect to the high importance of energy concept, limitation of natural resources, regulation of environmental issues, and global warming, heat transfer systemschr(chr('39')39chr('39')) applications get more attention. In the present paper, the experimental effect of Nano-fluid and turbulator on the heat transfer and pressure drop is investigated. AL2O3-SN300 base oil as nanoflu...
