This is because the single nozzle have not provided sufficient cooling and lubrication action at main cutting zone, and thereby produce more temperature. As a results, the tool wear is increased. This concept is also similar for nano-MQL conditions and double jet produce more better results as compared to single jet of nozzle.

Get Price2019-6-20 · In this study, effects of extended jet holes to heat transfer and flow characteristics of jet impingement cooling were numerically investigated. Cross-flow in the impinging jet cooling adversely affects the heat transfer on the target surface. The main purpose of this study is to reduce the negative effect of cross-flow on heat …
Get Price2008-8-30 · In each step the number of core and effect components and their overfeed levels were changed to determine the suitable air-jet texturing parameters in order to keep the parallel structure of the filaments as much as possible with no significant mechanical loss. In air-jet texturing, changing the core yarn overfeed has a direct influence on the strength of the textured yarn while the effect …

Löschner et al. studied the effect of jet traverse speed on surface quality in AWJM of 10-mm thick 316L stainless steel. In their experimental study, they demonstrated that jet …
Get Price2016-9-8 · Therefore it is not surprising that they have been frequently investigated both numerically and experimentally. In the study of Etemoglu et al. , an investigation is carried out to determine the effect of nozzle shape and size on heat transfer under impinging air jets. Experimental results show that the discharged coefficient only varies with velocity and nozzle shapes but not with the nozzle …
Get Price2018-12-11 · The combustor adds heat energy to the air stream and increases its temperature (up to about 1930°C), a process which is accompanied by a slight decrease in pressure (~ 1-2%). For best performances, the combustion temperature should be the maximum obtainable from the complete combustion of the oxygen and the fuel.
Get Price2021-1-30 · Based on the theoretical calculations made in the heating system design, literature studies [14,15,16,17] have been examined in detail to determine the nozzle diameter and size, and in order to determine the nozzle size that can provide a laminar flow after the combination of heated air and erosive particles in the nozzle; a design with a nozzle …
