Overview

What is he best known for?

The fields of study he is best known for:

  • Mathematical analysis
  • Thermodynamics
  • Mechanics

His scientific interests lie mostly in Porous medium, Thermodynamics, Mechanics, Capillary pressure and Multiphase flow. In his works, William G. Gray undertakes multidisciplinary study on Porous medium and Momentum. His work on Convection as part of general Thermodynamics research is frequently linked to Multi phase, bridging the gap between disciplines.

William G. Gray has included themes like Classical mechanics, Geotechnical engineering, Permeability and Darcy's law in his Mechanics study. His Capillary pressure research incorporates elements of Wetting, Relative permeability and Buckley–Leverett equation. The study incorporates disciplines such as Fluid mechanics and Two-phase flow in addition to Multiphase flow.

His most cited work include:

  • General conservation equations for multi-phase systems: 1. Averaging procedure (605 citations)
  • Thermodynamic basis of capillary pressure in porous media (526 citations)
  • Finite Element Simulation in Surface and Subsurface Hydrology (492 citations)

What are the main themes of his work throughout his whole career to date?

William G. Gray spends much of his time researching Porous medium, Mechanics, Finite element method, Mathematical analysis and Flow. His Porous medium research integrates issues from Multiphase flow, Thermodynamics, Statistical physics and Two fluid. His work in the fields of Mechanics, such as Fluid dynamics, intersects with other areas such as Momentum.

His Finite element method research incorporates elements of Quadratic equation and Wave equation. His research investigates the connection with Shallow water equations and areas like Applied mathematics which intersect with concerns in Mathematical optimization. He has researched Extended finite element method in several fields, including Smoothed finite element method and Finite difference coefficient.

  • Porous medium (36.10%)
  • Mechanics (26.14%)
  • Finite element method (14.94%)

What were the highlights of his more recent work (between 2014-2020)?

  • Porous medium (36.10%)
  • Mechanics (26.14%)
  • Two fluid (7.05%)

In recent papers he was focusing on the following fields of study:

William G. Gray mostly deals with Porous medium, Mechanics, Two fluid, Flow and Capillary pressure. His Porous medium research incorporates themes from Multiphase flow, Statistical physics and Euler characteristic. His Multiphase flow research is multidisciplinary, incorporating perspectives in Connection, Mathematical optimization and Thermal equilibrium.

His Mechanics study incorporates themes from Isothermal process and Minification. His Flow study combines topics in areas such as Mean curvature, State function and Applied mathematics. The various areas that William G. Gray examines in his Capillary pressure study include Function and Lattice Boltzmann methods.

Between 2014 and 2020, his most popular works were:

  • Mathematical tools for changing spatial scales in the analysis of physical systems (131 citations)
  • Geometric state function for two-fluid flow in porous media (42 citations)
  • On the dynamics and kinematics of two-fluid-phase flow in porous media (37 citations)

In his most recent research, the most cited papers focused on:

  • Mathematical analysis
  • Thermodynamics
  • Mechanics

His primary scientific interests are in Porous medium, Mechanics, Capillary pressure, Two fluid and Flow. His study in Porous medium is interdisciplinary in nature, drawing from both Multiphase flow, Statistical physics and Euler characteristic. His research in Multiphase flow intersects with topics in Thermal equilibrium, Connection, Closure, Mathematical optimization and Applied mathematics.

His Statistical physics study combines topics from a wide range of disciplines, such as Slip, Spurious relationship and SPHERES. His work in Capillary pressure addresses issues such as Lattice Boltzmann methods, which are connected to fields such as Relaxation, Thermodynamic equilibrium, Classical mechanics and Kinematics. The concepts of his Flow study are interwoven with issues in Mean curvature and State function.
