In the current research, numerical analysis was used to investigate flow behavior through axial jet-pump with various mixing chamber configurations (straight pipe and straight pipe-diffuser-straight pipe) in presence of inlet swirling its influence on pump performance. The effects introducing suction motive line, are numerically investigated. optimum swirl angle is found be 45o which yields max...
In liquid chromatography, baseline noise should be as low as possible to provide an optimum signal-to-noise ratio and to enable reliable integration of peaks at trace level. Baseline noise has different sources. One source is the detector, and another is the mixing performance of the pump, which is especially important if, for example, trifluoroacetic acid (TFA) is used as modifier in the mobil...
The introduction of brilliant free-electron lasers enables new pump-probe experiments to characterize warm dense matter states. For instance, a short-pulse optical laser irradiates a liquid hydrogen jet that is subsequently probed with brilliant soft x-ray radiation. The strongly inhomogeneous plasma prepared by the optical laser is characterized with particle-in-cell simulations. The interacti...
Coalbed methane extraction promotes energy exploitation and alleviates the greenhouse effect. This study aimed to analyze technical potential of a high-pressure gas–liquid two-phase jet in increasing coalbed permeability promoting extraction. A well-designed experimental setup was used investigate erosion characteristics jet. Through shock pressure monitoring tests jet, effects pump pressure, m...
The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...
