متن کاملALAQS- CFD Comparison of Buoyant Free and Wall Turbulent Jets
This report investigates the effects of a solid boundary on the flow properties of a buoyant jet. A comparison was made with the results of a previous ALAQS report on an unbounded jet to highlight the difference jet behaviours. It is believed that the inclusion of the wall represents a further step towards a better understanding of the source dynamics behind an airplane jet engine during the ta...
متن کاملSimple mixing criteria for the growth of negatively buoyant phytoplankton
Phytoplankton population dynamics are controlled by the relative rather than absolute timescales of mixing, growth, and loss processes such as sedimentation, grazing, and so on. Here, the vertical distribution and biomass of phytoplankton populations are quantified by two timescale ratios: the Peclet number Pe—the ratio of mixing and sedimentation timescales—and the growth number G—the ratio of...
متن کاملevaluation of effective parameters on buoyant jets development in the stagnant ambient fluid
abstract in the present article, effective parameters of the buoyant jets have been evaluated in the stagnant ambient fluid. the jet parameters, geometry parameters and environmental parameters are investigated. using dimensional analysis, a set of dimensionless functions was obtained. to achieve the exact functions, a physical model was built in the hydraulic laboratory of shahid chamran unive...
