A combined photovoltaic-thermal (PV-T) panel produces simultaneously electricity and heat from one integrated component to utilize effectively the solar energy by achieving higher PV electrical efficiency and making use ...
A compact procedure for discretization of the anisotropic diffusion operator

Darwish M.; Moukalled F. (PHILADELPHIA325 CHESTNUT ST, SUITE 800, PHILADELPHIA, PA 19106 USA, 2009)

This article presents a conservative finite-volume-based scheme for discretization of the anisotropic diffusion operator, which is simple to implement and numerically conservative. The procedure is an extension of a standard ...
A comparative assessment within a multigrid environment of segregated pressure-based algorithms for fluid flow at all speeds

Darwish M.; Asmar D.; Moukalled F. (, 2004)

This article deals with the evaluation of six segregated high-resolution pressure-based algorithms, which extend the SIMPLE, SIMPLEC, PISO, SIMPLEX, SIMPLEST, and PRIME algorithms, originally developed for incompressible ...
A coupled finite volume solver for compressible flows

Darwish M.; Moukalled F. (MELVILLE2 HUNTINGTON QUADRANGLE, STE 1NO1, MELVILLE, NY 11747-4501 USA, 2011)

This paper reports on the initial results of a coupled pressure-based algorithm for the solution of compressible flow problems at the subsonic regimes. The methods expands the application of a previous derived coupled ...
A coupled finite volume solver for incompressible flows

Moukalled F.; Darwish M. (, 2008)

This paper reports on a pressure-based coupled algorithm for the solution of laminar incompressible flow problems. The implicit pressure-velocity coupling is accomplished by deriving a pressure equation in a way similar ...
A coupled finite volume solver for the solution of incompressible flows on unstructured grids

Darwish M.; Sraj I.; Moukalled F. (SAN DIEGO525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA, 2009)

This paper reports on a newly developed fully coupled pressure-based algorithm for the solution of laminar incompressible flow problems on collocated unstructured grids. The implicit pressure-velocity coupling is accomplished ...
A coupled incompressible flow solver on structured grids

Darwish M.; Sraj I.; Moukalled F. (PHILADELPHIA325 CHESTNUT ST, SUITE 800, PHILADELPHIA, PA 19106 USA, 2007)

This article deals with the formulation, implementation, and testing of a fully coupled velocity-pressure algorithm for the solution of laminar incompressible flow problems. The tight velocity-pressure coupling is developed ...
A dimensional tolerancing knowledge management system using Nested Ripple Down Rules (NRDR)

Hamade R.F.; Moulianitis V.C.; D'Addonna D.; Beydoun G. (OXFORDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2010)

This paper proposes to use a knowledge acquisition (KA) approach based on Nested Ripple Down Rules (NRDR) to assist in mechanical design focusing on dimensional tolerancing. A knowledge approach to incrementally model ...
A flexible-link model for compliant member synthesis

Smaili A.; Hassanieh M. (, 2006)

A new approach for the synthesis of a compliant link experiencing nonlinear deformations is herein introduced. The model is being proposed as an alternative to the pseudo-rigid-body model widely used in compliant mechanisms ...
A fully coupled navier-stokes solver for fluid flow at all speeds

Darwish M.; Moukalled F. (Taylor and Francis Inc.; PHILADELPHIA520 CHESTNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA, 2014)

This article deals with the formulation and testing of a newly developed, fully coupled, pressure-based algorithm for the solution of fluid flow at all speeds. The new algorithm is an extension into compressible flows of ...
A geostatistical approach for assessing population exposure to NO2 in a complex urban area (Beirut, Lebanon)

Badaro-Saliba N.; Adjizian-Gerard J.; Zaarour R.; Abboud M.; Farah W.; Saliba N.A.; Shihadeh A. (NEW YORK233 SPRING ST, NEW YORK, NY 10013 USA, 2014)

Few studies in the Middle East region estimated the spatial distribution of air pollutants for exposure studies. This paper presents a geostatistical approach to assess background NO2 spatial distribution and the associated ...
A high resolution spatially adaptive vortex method for separating flows. Part I: Two-dimensional domains

Lakkis I.; Ghoniem A. (SAN DIEGO525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA, 2009)

A hybrid ankle-hip preemptive falling scheme for humanoid robots

Jalgha B.; Asmar D.; Elhajj I. (, 2011)

If we are to one day rely on robots as assistive devices they should be capable of mitigating the impact of random disturbances and avoid falling. Humans are surprisingly apt at remaining on their feet when pushed; they ...
