RISSolute Transport due to Spatio-Temporally Dependent Dispersion Coefficient and Velocity: Analytical Solutions
Publisher: American Society of Civil Engineers
Abstract: This paper presents an analytical solution of the advection-dispersion equation (ADE) with the dispersion coefficient and velocity being directly proportional to the spatial linear nonhomogeneous function. It is one of the ...
Investigations on the Tribological Characteristics of TiO2-Doped Nanofluid Fuel (Biodiesel/Diesel Blend) at Different Contact Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fuels (diesel/biodiesel blends) for diesel engines must possess a minimum of lubricating characteristics to prolong the life of some of the engine vital parts lubricated by the fuel itself. Hence, the tribological ...
Effect of Punched-Hole Electrodes on the Performance of Electrocoagulation
Publisher: ASCE
Abstract: Textile industries are water intensive and the effluent generated contains salts, dyes, and heavy metals as well as having a high biological oxygen demand (BOD) and chemical oxygen demand (COD), therefore it must be treated ...
Analytical Solution of Advection-Dispersion Equation with Spatially Dependent Dispersivity
Publisher: American Society of Civil Engineers
Abstract: In the dispersion theory of solute transport in groundwater flow, the dispersion coefficient is regarded as proportional to the nth power of groundwater velocity, where n varies from 1 to 2. The present study derives an ...
Corner Reproduction Accuracy in Electro-Chemical Drilling (ECD) of Blind Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Little information is available about the corner shape and size produced in electrochemical drilling of blind holes. On this account prediction of the complete anode shape analytically, in ECD, ...
Numerical Solution of 2D Free Surface Flow to Ditch Drains in Anisotropic Soils
Publisher: American Society of Civil Engineers
Abstract: A numerical solution of two-dimensional free surface flow to ditch drains in homogeneous and anisotropic soils is presented. The differential equation governing two dimensional ground-water flow in anisotropic soils is ...

Rotating Flow and Heat Transfer in Cylindrical Cavities With Radial Inflow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design and optimization of an efficient internal air system of a gas turbine requires a thorough understanding of the flow and heat transfer in rotating disc cavities. The present study is devoted to the numerical ...
Thermo-Fluid Design Simulation of Nd3+ POCl3 Transverse Flow Liquid Laser Cavity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) based thermal design of a transverse flow optical cavity is carried out for 1 kW Nd3+ POCl3 liquid laser source to investigate temperature and velocity distribution in the optical pumping ...
Assessment of Radionuclide Concentration and Radiation Dose in Rock in Singrauli Coalfield, India
Publisher: ASCE
Abstract: This study was conducted at the Singrauli coal mine environment in Singrauli coalfield, India. The activity concentrations of thorium (Th232), uranium (U238), and potassium (K40) in rock samples were analyzed by gamma ...
