RISModeling Water Movement and Flux from Membrane Pervaporation Systems for Wastewater Microirrigation
Publisher: American Society of Civil Engineers
Abstract: A mathematical model to predict the performance of a membrane pervaporation unit directly placed in the soil to reuse wastewater for agricultural microirrigation was presented. The model was formulated by combining the ...
Kinetics of Ozone Disinfection in Completely Mixed System
Publisher: American Society of Civil Engineers
Abstract: Development of models that describe inactivation kinetics with ozone is made difficult by unstable ozone residual, rapid rate of inactivation process, and improper interpretation of inactivation data. Consequently, there ...
Effect of Turning Vane Configurations on Heat Transfer and Pressure Drop in a Ribbed Internal Cooling System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ribbed serpentine blade cooling system is a typical configuration in the modern gas turbine airfoil. In this study, experimental and the numerical efforts were carried out to investigate ...
Coupled Aerothermodynamics Optimization for the Cooling System of a Turbine Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cooling system design for aircooled turbines is a critical issue in modern gas turbine engineering. Advances in the computational fluid dynamics (CFD) technology and optimization methodology are providing new prospects ...
Film Cooling Modeling of Turbine Blades Using Algebraic Anisotropic Turbulence Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The complex structures in the flow field of gas turbine film cooling increase the anisotropy of turbulence making it difficult to accurately compute turbulent eddy viscosity and scalar diffusivity. An algebraic anisotropic ...
Membrane Pervaporation for Wastewater Reuse in Microirrigation
Publisher: American Society of Civil Engineers
Abstract: A novel wastewater microirrigation technology for plants to extract reclaimed water from hydrophilic, homogenous dense membrane modules placed directly in the soil was evaluated. A series of tests were conducted in the ...
Experimental Investigation of Endwall Heat Transfer With Film and Impingement Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The switch from diffusive combustion to premixed combustion in a modern gas turbine changes the combustor exit temperature profile to a more uniform one. This will directly affect the cooling of the first stage vane ...
Effect of Reynolds Number, Hole Patterns, and Target Plate Thickness on the Cooling Performance of an Impinging Jet Array—Part II: Conjugate Heat Transfer Results and Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study comprehensively illustrates the effect of Reynolds number, hole spacing, nozzle-to-target distance, and target plate thickness on the conjugate heat transfer (CHT) performance of an impinging jet array. Test ...
