RISAir Cooling of Variable Array of Heated Modules in a Vertical Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of array size and substrate thermal conditions upon heat transfer characteristics of an array of heated modules subjected to buoyancy assisted convection cooling in air is investigated. ...
Convective Cooling of a PCB Like Surface With Mixed Heating Conditions in a Vertical Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Printed circuit boards (PCBs) with uniform surface temperature and uniform wall heat flux are ideal to study. However, in reality, the heating conditions existing on the PCB surfaces are much ...
Assembly Free Large Scale Modal Analysis on the Graphics Programmable Unit
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Popular eigensolvers such as blockLanczos require repeated inversion of an eigenmatrix. This is a bottleneck in largescale modal problems with millions of degrees of freedom. On the other hand, the classic Rayleigh–Ritz ...
Large Scale Finite Element Analysis Via Assembly Free Deflated Conjugate Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Largescale finite element analysis (FEA) with millions of degrees of freedom (DOF) is becoming commonplace in solid mechanics. The primary computational bottleneck in such problems is the solution of large linear systems ...
Experimental Validation of Analytical Solutions for Vertical Flat Plate of Finite Thickness Under Natural-Convection Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analytical solution for a vertical heated plate subjected to conjugate heat transfer due to natural convection at the surface and conduction below is presented. The heated surface is split ...
Removal Comparison and Cost Evaluation of 2,6-Dichlorophenol
Publisher: ASCE
Abstract: In this study, 2,6-dichlorophenol (2,6-DCP), 5 mg/L was targeted as a priority pollutant and removed using chemical coagulation (CC), adsorption (AD), and electrocoagulation (EC) processes. Aluminum sulfate (AS) and ferrous ...
Comparison of Single and Multiple Injection Strategies in a Butanol Diesel Dual Fuel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A turbocharged three cylinder automotive common rail diesel engine was modified to operate in the n-butanol diesel dual fuel mode. The quantity of butanol injected by the port fuel injectors and the rail pressure, injection ...
Characterization of Free-Fall Dust Aerosols at Two Different Heights in Delhi: Understanding the Influence of Carbon Fraction
Publisher: American Society of Civil Engineers
Abstract: The free-fall dust in ambient atmosphere provides important information about the nature and sources of pollutants in urban settings, because it incorporates the particles settling under gravity influence irrespective of ...
Elemental Composition and Source Apportionment of Suspended Particulate Matters and Health Risk Assessment in Mining and Nonmining Areas of Odisha, India
Publisher: American Society of Civil Engineers
Abstract: Atmospheric particulate matter was sampled synchronously during a monitoring campaign from January–December 2010 in mining and nonmining areas in Odisha, India. In this study, 14 elements were observed in suspended particulate ...
Nucleation and Boundary Layer Growth of Shear Bands in Machining
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: We demonstrate a novel approach to study shear banding in machining at low speeds using a low melting point alloy. In situ imaging and an image correlation method, particle image velocimetry (PIV), are used to capture shear ...
