An Investigation of an Affordable Ventilation Retrofit to Improve the Indoor Air Quality in Australian Aged Care Homes
Publisher: American Society of Civil Engineers
Abstract: Residents in aged care homes constitute a significant proportion of Australia’s population. The elderly population is vulnerable to poor indoor air quality (IAQ). Because mobility declines with age, they tend to spend ...
Active Control of Tip Clearance Flow in Axial Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Control of compressor tip clearance flows is explored in a linear cascade using three types of fluidic actuators; normal synthetic jet (NSJ; unsteady jet normal to the mean flow with zero net ...
Effect of Injection Strategy on the Combustion and Exhaust Emission Characteristics of a Biodiesel-Ethanol Blend in a DI Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation was performed on the effect of injection strategy on the combustion, exhaust emission characteristics and the particle size distribution in a small direct-injection ...
Numerical Simulation of Shallow-Water Flow Using a Modified Cartesian Cut-Cell Approach
Publisher: American Society of Civil Engineers
Abstract: The Cartesian cut-cell method can be used to represent irregular and complex computational domains with less computational efforts by cutting the grid cells on the boundary surfaces in a background uniform Cartesian mesh. ...
Effect of Pore Architecture on Oxygen Diffusion in 3D Scaffolds for Tissue Engineering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this study was to maximize oxygen diffusion within a three-dimensional scaffold in order to improve cell viability and proliferation. To evaluate the effect of pore architecture on ...
Characteristics of Particulate Emissions of Compression Ignition Engine Fueled With Biodiesel Derived From Soybean
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation was performed on the effect of engine speed, exhaust gas recirculation (EGR), and boosting intake pressure on the particulate size distribution and exhaust gas ...
Thermal Performance Measurement of a Bump Type Gas Foil Bearing Floating on a Hollow Shaft for Increasing Rotating Speed and Static Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Identifying thermal characteristics of gas foil bearings (GFBs) provides an insight for successful implementation into high speed oil-free turbomachinery. The paper presents temperature measurements ...
New Line Accuracy Assessment Methodology Using Nonlinear Least-Squares Estimation
Publisher: American Society of Civil Engineers
Abstract: This paper presents a novel line accuracy assessment technique by measuring the offsets of a typical measured line from the true reference line. These measurements are assumed to follow a Gaussian distribution. Buffers of ...
Upstream Jet Cooling and Dual Cavity Slashface Leakage Cooling on a Transonic Nozzle Guide Vane Endwall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental and computational study on implementing a dual cavity slashface cooling scheme on the thermal performance for the first stage nozzle guide vane with an axisymmetric, converging endwall. ...
