In this work it has been attempted to study the dynamic behavior of a double pipe heat exchanger both experimentally and theoretically. The double pipe heat exchanger configuration simulated consisted of two
concentric pipes, the outer pipe carries the hot fluid and the inner pipe carries cold fluid and the circulation of the two fluids is made by two pumps. The influence of the following variables studied are the flow
Experimental work is carried out to study behavior of mixture of mixing of two types of waxes (paraffin and microcrystalline) and different types of heavy oil (base stock 40, base stock 60, base stock 150, furfural extract 60 and furfural extract 150).The experimental work included the determination of important properties of mixture which are drop point, penetration, and copper corrosion.Also the experimental work included the investigation of the effect of wax weight percentage, wax type and heavy oil type on these properties of mixture.Various types of mixtu
Laser and electron beams are presently widely applied to many fields of material processing. Laser and electron beams produce the highest heat sources intensities used in welding process.This work investigates analytical comparison which discusses the differences and similarities between laser and electron beam welding.These comparisons have been made in three aspects. The first explains the main
