RISEffects of pH and Surfactant on the Forced Convection of Al2O3/Water and TiO2/Water Nanofluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper deals with the forced convection of Al2O3/water and TiO2/water nanofluids with the variation of pH and addition of surfactant in nanofluids. The aim of this study is to investigate the effect of suspension ...
Theoretical Study on Falling Film Fin-Tube Dehumidifier Integrated With an Evaporative Cooler
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current work presents the theoretical analysis of a falling film fin-tube dehumidifier integrated with an evaporative cooler using CaCl2 as a liquid desiccant. In a fin-tube dehumidifier, the fins are provided outside ...
Two-Phase Flow Pressure Drop in Right Angle Bends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas-liquid two-phase bubbly flows in right angle bends have been studied. Numerical predictions of the flow in right angle bends are made from first principles using an Eulerian-Eulerian two-fluid ...
Effect of Spatially Varying Magnetic Field on the Cooling of an Electronic Component by Natural Convection With Magnetic Nanofluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural convection cooling of an electronic component in an electronic device using water-based Fe3O4 magnetic nanofluids is studied under the presence of the magnetic field. The heated vertical electronic component in an ...
Heat Transfer and Pressure Drop Performance of Al2O3/Water and TiO2/Water Nanofluids in Tube Fitted With Simple or Modified Spiral Tape Inserts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper deals with the forced convection and pressure drop of Al2O3/water and TiO2/water nanofluids with the presence of inserts in a circular tube. The constant heat flux is maintained around the copper tube ...
Influence of Osmotic Suction on the Soil-Water Characteristic Curves of Compacted Expansive Clay
Publisher: American Society of Civil Engineers
Abstract: Unsaturated clays are subject to osmotic suction gradients in geoenvironmental engineering applications and it therefore becomes important to understand the effect of these chemical concentration gradients on soil-water ...
Removal of Endosulfan from Water Using Wood Charcoal—Adsorption and Desorption
Publisher: American Society of Civil Engineers
Abstract: Endosulfan, one of the most widely used pesticides in various sectors including agriculture, has been reported posing a threat to the ecology as well as to the environment. Contamination of groundwater and surface water ...
Role of Fly Ash Pozzolanic Reactions in Controlling Fluoride Release from Phosphogypsum
Publisher: American Society of Civil Engineers
Abstract: Phosphogypsum is added to building materials to accelerate fly ash pozzolanic reaction and contributes to early strength development of concrete. The release of unacceptable fluoride levels by phoshogypsum on contact with ...
Transient Analysis of Nonuniform Heat Input Propagation Through a Heat Sink Base
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For thermal management architectures wherein the heat sink is embedded close to a dynamic heat source, nonuniformities may propagate through the heat sink base to the coolant. Available transient models predict the effective ...
Activation of Fly Ash–Lime Reactions: Kinetic Approach
Publisher: American Society of Civil Engineers
Abstract: Lime–fly ash reactions play a key role in improving the mechanical strength and tailoring the permeability characteristics of compacted fly ash. Activation of fly ash–lime pozzolanic reactions should accelerate the rate ...
