RISMechanical Erosion Investigation in Solid Rocket Motor Nozzle Through Droplet Breakup and Surface Tension Influence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Erosion prediction of the solid propellent nozzle is vital for its design process. This erosion is caused by the impingement of agglomerated aluminum/aluminum oxide particles on the nozzle walls. Thus, a multi-phase numerical ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a detailed investigation into enhancing the energy efficiency of wastewater treatment plants (WWTPs) by integrating photovoltaic (PV) systems, emphasizing power flow analysis and experimental validation. ...
Experimental Study on Rotating Spar Mixer in Energy-Efficient Aeration Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Aeration is a critical and energy-intensive process in wastewater treatment, and its efficiency is strongly influenced by bubble size. In this study, a novel rotating spar mixer is proposed to generate smaller ...
Investigation of Frosting Performance on Air-Sourced Heat Pump Evaporator for Cold Climate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Frost formation on the evaporator surface of air-source heat pumps (ASHPs) operating in cold climates significantly degrades heat-transfer performance and increases compressor power consumption. Accurate prediction ...
Investigation of Flow Over an Airfoil Using a Hybrid Detached Eddy Simulation–Algebraic Stress Turbulence Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbulent air flow over an NACA 4412 airfoil is investigated computationally. To overcome the near-wall inaccuracies of higher order turbulence models such as large Eddy simulation (LES) and detached Eddy simulation (DES), ...
Improvement of Aerodynamic Performance of Cambered Airfoils Using Leading-Edge Slots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Feasibility of increasing lift and decreasing drag by drilling narrow span-wide channels near the leading edge of NACA 4412 airfoils is investigated. It is proposed to drill two-segment slots that allow some of the incoming ...
