RISPerformance Assessment of Different Turbulence Models for a Dual Jet Flowing Over a Heated Sinusoidal Wavy Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An enhancement in heat transfer is the key objective in any thermal system where an efficient cooling is needed. This requirement becomes more important for turbulent flow. A turbulent dual jet is associated with entrainment ...
A Three-Equation Variant of the SST k-ω Model Sensitized to Rotation and Curvature Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new variant of the SST k-ω model sensitized to system rotation and streamline curvature is presented. The new model is based on a direct simplification of the Reynolds stress model under ...
Estimation of Tensile Strength of Soils from Penetration Resistance
Publisher: American Society of Civil Engineers
Abstract: Tensile strength of soil plays a decisive role in formation/initiation of cracks and their propagation, and its knowledge is essential to study and analyze the stability of earth-fill dams, slopes, embankments, highways, ...
Entropy Generation in Water-Based Natural Circulation Loop
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural circulation loop (NCL) based secondary fluid systems are simple, reliable, and inexpensive due to the absence of any moving components such as pumps. Water-based NCLs are widely used in applications such as solar ...
Batch and Column Performance of Fluoride Adsorption by Java Plum Seeds
Publisher: American Society of Civil Engineers
Abstract: The present study used techniques such as batch and fixed-bed column adsorption techniques to explore the removal of fluoride from industrial waste water through the means of a bioadsorbent (Java plum seeds). The minimum ...
Comparison of Properties of Defluoridation of <i>Ipomoea aquatica</i> and <i>Eichhornia crassipes</i> by Means of Phytoremediation
Publisher: American Society of Civil Engineers
Abstract: The authors study two species of plant—water hyacinth (Eichhornia crassipes) and water spinach (Ipomoea aquatica). These plants are commonly found in aquatic bodies such as lakes, ponds, and rivers. Both plants are grown ...
Role of a Sinusoidal Wavy Surface in Enhancement of Heat Transfer Using Turbulent Dual Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the role of sinusoidal wavy surface in enhancing the heat transfer is numerically studied. The heat transfer characteristics are studied for two thermal boundary conditions of the wavy wall. To assess the ...
Elliptical Bladed Savonius Rotor for Wind Energy: Efficacy of RANS Modeling for Flow Characteristics
