THEORETICAL AND EXPERIMENTAL INVESTIGATIONS OF MULTIPLE INCLINED JETS

Prajapat, M. / Eldho, T. I.

Different researchers have investigated turbulent jets with several theories such as Reichardt's theory, point source concept and experimental results. For the case of parallel jets, earlier investigators have proved reliability of these methods with their experimental data, but for inclined jets, not many studies are reported. The present study focuses on verifying theoretical results with experimental data, for different cases of inclinations and holes spacing of two jets. For theoretical solution, starting from the solution of a single jet given by Reichardt, point source concept is applied and theoretical result for inclined jets is derived. For experimental investigations, a setup existing in Hydraulics Laboratory, IIT Bombay has been modified to make two inclined jets with a blower. A pair of nozzle is made with 2 degrees of freedom—lateral movement and rotation. Initially the setup is checked for parallel jets and results are compared with theory and earlier results. Further experiments with different inclinations and holes spacing are carried out. Experimental and theoretical results are compared and better agreement is observed for closely spaced inclined jets.
