HEAT EXCHANGE BEAM SEMI-CYLINDRICAL PIPE WITH INTENSI- FIERS. 2. CALCULATION OF HYDRAULIC RESISTANCE.
Abstract
The mathematical model and calculation of hydraulic resistance for chess beam pipe in the presence of semi-cylindrical intensifiers on the outer surface. The dependences of the hydraulic resistance coefficient from the distance between the intensifier for the studied surfaces. Comparison of calculation results with experimental data for pipes intensifiers is made. It is shown that the use of intensifiers in- creases the hydraulic resistance of such surfaces compared with smooth surfaces. It is found that a geometry placement of intensifiers on the surface and size of Rey- nolds number in the external flow has a significant influence on the value of hydrau- lic resistance.
