Experimental Investigation of Thermal and Hydraulic Performance of a Plate Heat Exchanger Using Nanofluids
(Springer New York LLC, 2019)
Gasketed plate heat exchangers (PHEs) occupy a crucial position in the energy sector due to their efficient and compact design. A number of studies have focused on making the plate heat exchangers more efficient and compact, ...
Effects of Active and Passive Control Techniques on Mach 1.5 Cavity Flow Dynamics
(Hindawi Ltd, 2017)
Supersonic flow over cavities has been of interest since 1960s because cavities represent the bomb bays of aircraft. The flow is transient, turbulent, and complicated. Pressure fluctuations inside the cavity can impede ...
Artificial Neural Network Based Prediction Of Time-Dependent Behavior For Lid-Driven Cavity Flows
(Turkish Soc Thermal Sciences Technology, 2015)
In this study, computational fluid dynamics (CFD) analyses of the two-dimensional, time-dependent lid-driven cavity flows, for Reynolds numbers ranging from 100 to 10000, are performed by using an in-house developed CFD ...
Comparative gasketed plate heat exchanger performance prediction with computations, experiments, correlations and artificial neural network estimations
(Hong Kong Polytechnic Univ, Dept Civil & Structural Eng, 2017-04-27)
Gasketed plate heat exchangers (GPHEX) are popular due to their small volume, ease of cleaning and high thermal performance. Hydraulic and thermal performance of GPHEX are not as easily determined since they solely depend ...
Numerical research of cavitation on Francis turbine runners
(Pergamon-Elsevier Science Ltd, 2017-07-13)
Francis turbines, as other hydraulic turbines, are custom-designed for nominal operating conditions specific to each power plant. However, they may need to be operated at off design flow conditions because of variable ...
Experimental investigation and CFD analysis of rectangular profile FINS in a square channel for forced convection regimes
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2016-11)
Steady-state heat transfer from rectangular fin arrays is examined experimentally and numerically for turbulent fully developed flow. The effects of geometrical parameters on heat transfer coefficient and Nusselt number ...
Aerodynamic Analysis Of A Vertically Landing Lifting Body
(Turkish Soc Thermal Sciences Technology, 2015)
The vertical landing lifting body (VLLB) is a new concept for reusable launch vehicles, which launches vertically, but re-enters the atmosphere at a high angle of attack (alpha) for its entire flight. The VLLB remains at ...
Determination and generalization of the effects of design parameters on Francis turbine runner performance
(Hong Kong Polytechnic Univ, Dept Civil & Structural Eng, 2016)
The runner design is the most challenging part of the turbine design process. Several parameters determine the performance and cavitation characteristics of the runner: the metal angle (flow beta angle), the alpha angle, ...
Design Of A Flow Diverter Mechanism And A Nozzle For A Hydro Turbine Experimental Test Rig
(Amer Soc Mechanical Engineers, 2014)
Hydro turbines used in hydroelectric power plants need to be designed and tested according to the specifications of the specific power plant, mainly the head and flow rate. Their models also need to be tested according to ...
A Combined Experimental And Computational Study For The Design Of A Low Water Consumption Cooling Tower
(Amer Soc Mechanical Engineers, 2014)
In this study, a combined experimental and computational study for the design of a low water consumption cooling tower is performed. The purpose of the study is to reduce the water consumption without decreasing the ...
