RISReduction of Jet Impingement Noise by Addition of Swirl
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental investigations are carried out with an objective of reducing impingement jet noise using coaxial swirl jets. Two nozzle-to-plate distances have been considered and the Mach number values ranged from 0.95 to ...
An Estimation of Optimum Grid Size for Kashmir Valley by Spectral Method
Publisher: American Meteorological Society
Abstract: In many of the short-range numerical weather prediction models, an accurate specification of grid size is essential in mountainous and valley regions to adequately represent terrain forcing without resorting to subgrid-scale ...
Simulation of Airflow in Kashmir Valley for a Summer Day
Publisher: American Meteorological Society
Abstract: The airflow over the Kashmir Valley for a summer day was studied using a numerical mesoscale model. Srinagar observations were used as initial data. The surface orography, soil moisture variations, cloud cover, and vegetation ...
Simulation Analysis and Material Optimization of an Aircraft Wing Leading Edge When Subjected to an Artificial Bird Strike
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bird strike resistance is a strict certification requirement in aircraft industries, and the Federal Aviation Regulations specifically gives various specifications to be followed for certification of various parts of the ...
Performance Analysis of Single-Phase Space Thermal Radiators and Optimization Through Taguchi-Neuro-Genetic Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the thermal management of spacecraft, space thermal radiators play a vital role as heat sinks. A serial radiator with proven advantages in ground applications is proposed and analyzed for space applications. From the ...
Shock–Boundary Layer-Interaction Control Through Recirculation in a Hypersonic Inlet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This technical brief presents a flow separation mitigation device, called cavity-recirculator that can be used to control flow separation during shock wave–boundary layer interaction (SBLI) in high-speed intake flows. The ...
Simulations With Compressible Multiphase Formulation on Heat Transfer Studies in a Rocket Thrust Chamber With Experimental Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the combustor for rocket engines, liquid film cooling is a widely adopted technique for restricting the structural components to the acceptable bounds for the successful operation of the propulsion systems. Multiple ...
Cyclic Combustion Variations in Dual Fuel Partially Premixed Pilot Ignited Natural Gas Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dual fuel pilotignited natural gas engines are identified as an efficient and viable alternative to conventional diesel engines. This paper examines cyclic combustion fluctuations in conventional dual fuel and in dual fuel ...
Experimental and Numerical Studies on Gas Flow Through Silicon Microchannels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work investigates the extension of Navier–Stokes equations from slip-to-transition regimes with higher-order slip boundary condition. To achieve this, a slip model based on the second-order slip boundary condition ...
Analysis of Ignition Behavior in a Turbocharged Direct Injection Dual Fuel Engine Using Propane and Methane as Primary Fuels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dual fuel engine combustion utilizes a highcetane fuel to initiate combustion of a lowcetane fuel. The performance and emissions benefits (low NOx and soot emissions) of dual fuel combustion are wellknown. Ignition delay ...
