Investigation of shell and tube heat exchangers by using a design of experiment

Heat exchangers are one of the most important devices of mechanical systems in modernsociety. Most industrial processes involve the transfer of heat and more often they requirethe heat transfer process to be controlled. A heat exchanger is the heat exchanged betweentwo media, one being cold and the other being hot. There are different types of heatexchanger, but the type which is widely used in...

Effectively Design Shell-and-Tube Heat Exchangers

heat exchangers (STHEs) is done by sophisticated computer software. However, a good understanding of the underlying principles of exchanger design is needed to use this software effectively. This article explains the basics of exchanger thermal design, covering such topics as: STHE components; classification of STHEs according to construction and according to service; data needed for thermal de...

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...
