SETTING STORAGE USING INFORM

SETTING STORAGE USING INFORM. To get acquainted with the In-Form syntax it is introduced by means of examples. To begin with, it is shown the ways to set storage and evaluate new variables using In-Form. A sequence of workshops presents distinct features of In-Form to store auxiliary variables.

Augmentation of Heat Transfer Performance with Aluminium and Copper Twisted Tape Inserts

An experimental investigation of heat transfer, friction factor and pressure drop characteristics in a pipe fitted with the Al twisted tape and cu twisted tape inserts with different twist ratio. The experimental work was conducted and the analysis of heat transfer was investigated with laminar flow. The experimental data were obtained from the double pipe heat exchanger with concentric tube fitted with insert of aluminium and copper material twisted tape inserts. The results of the Al and cu were investigated and compared these two results. The results shows that the heat transfer enhanced in the copper material inserts compared to Aluminium material inserts. The heat transfer augmentation was enhanced with 1.1 to 1.3 times compared to the Aluminium. The experimental results reveal that the different material of inserts. The Reynolds number various from 2570 to7891. The twist ratio of both the material is y = 4.3.
