Helically Coiled Heat Exchangers

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...

Optimal Design of Shell-and-Tube Heat Exchanger Based on Particle Swarm Optimization Technique

The paper studies optimization of shell-and-tube heat exchangers using the particle swarm optimization technique. A total cost function is formulated based on initial and annual operating costs of the heat exchangers. Six variables – shell inside diameter, tube diameter, baffle spacing, baffle cut, number of tube passes and tube layouts (triangular or square) – are considered as the design para...
