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, ...
CFD-driven surrogate-based multi-objective shape optimization of an elbow type draft tube
(Pergamon-Elsevier Science Ltd, 2017-07-13)
Draft tube is the part of Francis turbines which is used to both discharge water and recover kinetic energy at the exit of the runner. A design optimization study of an elbow type draft tube based on the combined use of ...
Experimental analysis of a mixed-plate gasketed plate heat exchanger and artificial neural net estimations of the performance as an alternative to classical correlations
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2016-11)
In this study, experiments are performed to test the thermal and hydraulic performance of gasketed plate heat exchangers (GPHE). A heat exchanger composed of two different plate types is used for the experiments, for a ...
Experimental comparison of performances of three different plates for gasketed plate heat exchangers
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2014-01)
In this study, an experimental set-up for testing chevron type gasketed plate heat exchangers is utilized to investigate the thermal and hydraulic characteristics of three different plate geometries. The experiments are ...
Experimental Investigation And Performance Analysis Of Gasketed-Plate Heat Exchangers
(Turkish Soc Thermal Sciences Technology, 2015)
In this study, the thermal and hydrodynamic performance analyses of sa elected gasketed-plate heat exchanger with different number of plates are performed experimentally. A gasketed-plate heat exchanger (GPHE) test set-up ...
CFD based design of a 4.3MW Francis turbine for improved performance at design and off-design conditions
(Korean Soc Mechanical Engineers, 2017-10)
Hydraulic turbines are designed for the available head and flow rate of the hydroelectric power plant. Design point usually gives the best efficiency. However, when the turbine is used at off-design conditions where the ...
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 ...
