RISQuantification of Modeled Streamflows under Climate Change over the Flint River Watershed in Northern Alabama
Publisher: American Society of Civil Engineers
Abstract: This study quantified the impacts of climate change on water availability over the Flint River subwatershed (FRW) located in the Wheeler Lake Watershed (WLW) in northern Alabama. The observed climate data were obtained ...
Use of Thermodynamic Formalism in Generalized Continuum Theories and a Model for Damage Evolution
Publisher: American Society of Civil Engineers
Abstract: A technique for setting up generalized continuum theories based on a balance law and nonlocal thermodynamics is suggested. The methodology does not require the introduction of gradients of the internal variable in the free ...
Spectral Simulation on the Flow Patterns and Thermal Control of Radiative Nanofluid Spraying on an Inclined Revolving Disk Considering the Effect of Nanoparticle Diameter and Solid–Liquid Interfacial Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current work enlightens the flow pattern and thermal scenario of a nanofluid spraying on an inclined permeable rotating disk. The whirling disk is assumed to revolve with the angular speed Ω. The water-based alumina ...
Framing the Impacts of Highly Oscillating Magnetic Field on the Ferrofluid Flow Over a Spinning Disk Considering Nanoparticle Diameter and Solid–Liquid Interfacial Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article communicates on the ferrofluid flow over a spinning disk in the presence of highly oscillating magnetic field. The flow is presumed to be unsteady. Ferrous nanoparticles are suspended within base medium water. ...
Wettability Effects on Falling Film Flow and Heat Transfer Over Horizontal Tubes in Jet Flow Mode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of a falling-film heat exchanger is strongly linked to the surface characteristics and the heat transfer processes that take place over the tubes. The primary aim of this numerical study is to characterize ...
Bend Geometries in Internal Cooling Channels for Improved Thermal Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pressure drop and heat transfer in a two pass internal cooling channel with two different bend geometries is experimentally studied with the goal of improving the thermal performance factor (TPF) in the coolant channel. ...
Experimental and Computational Study of Heat/Mass Transfer and Flow Structure for Four Dimple Shapes in a Square Internal Passage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mass/heat transfer measurements are made using the naphthalene sublimation method in a square internal passage where one wall has a single dimple. Four types of dimple shapes are studied: square, ...
Heat Transfer at High Rotation Numbers in a Two-Pass 4:1 Aspect Ratio Rectangular Channel With 45deg Skewed Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat transfer measurements are reported for a rotating 4:1 aspect ratio (AR) coolant passage with ribs skewed 45deg to the flow. The study covers Reynolds number (Re) in the range of ...
Effect of Bend Geometry on Heat Transfer and Pressure Drop in a Two Pass Coolant Square Channel for a Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a comparative numerical study of turbulent flow inside a twopass internal cooling channel with different bend geometries. The goal is to find a geometry that reduces the bend related pressure loss and ...
Turbine Blade Tip Film Cooling With Blade Rotation—Part I: Tip and Pressure Side Coolant Injection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study of film cooling is conducted on the tip of a turbine blade with a blade rotation speed of 1200 rpm. The coolant is injected from the blade tip and pressure side (PS) holes, and the effect of the ...
