Prof. Amr Guaily is a university professor and the director of the mechanical engineering program (MENG) at School of Engineering and Applied Sciences, at Nile University and is the former director of the Smart Engineering Systems Research Center (SESC). He received his B.Sc. and M.Sc. degrees from Cairo University, Egypt in 2002 and 2006, respectively. In 2011, he obtained his Ph.D. in mechanical and manufacturing engineering from the University of Calgary, Canada. The research interests are fluid dynamics with emphasis on both the numerical simulation and mathematical modelling of viscoelastic fluids and molten salts, and the use of the level set technique for studying fluid/structure interaction.

Active Morphing Control of Airfoil At Low Reynolds Number Using Level-Set Method
The active control of flow around an airfoil through morphing is numerically investigated. The lock-in phenomenon was predicted while using a fixed grid. Galerkin/Least-Squares Finite Element Method was used to simulate incompressible flow over an airfoil with leading edge morphing at a Reynolds number, Re = 5000, and angle of attack, α = 6°. The numerical simulation was carried out using the in
Turbulent Axisymmetric Non-Isothermal Flow of the Hitec Molten Salt with Temperature Dependent Properties: A Numerical Investigation
Comparative Study for Different URANS Models for Capturing Flow Separation Inside a Plane Diffuser
A comparative numerical study is performed among different URANS turbulence models investigating the ability of the models to capture the deformation of the boundary layer near the separation zone. The results are validated against previously published numerical works (URANS, LES, DNS) and experimental works. The comparison included grid resolution, the pressure distribution, and the velocity
Air change rate effects on the airborne diseases spreading in Underground Metro wagons
Stabilized variational formulation of an oldroyd-B fluid flow equations on a Graphic Processing Unit (GPU) architecture
The governing equations of the flow of an oldroyd-B fluid are discretized using the finite element method. To overcome the convective nature of the momentum equation, the Galerkin/Least-Squares Finite Element Method (GLS/FEM) is used while the Discrete Elastic–Viscous Stress-Splitting (DEVSS) method is used to overcome the instability due to the absence of diffusion in the constitutive equations
A Stress Mapping Immersed Boundary Method for Viscous Flows
This work introduces an immersed boundary method for two-dimensional simulation of incompressible Navier-Stokes equations. The method uses flow field mapping on the immersed boundary and performs a contour integration to calculate immersed boundary forces. This takes into account the relative location of the immersed boundary inside the background grid elements by using inverse distance weights
Regression Modeling for the Ventilation Effect on COVID-19 Spreading in Metro Wagons
The effect of different ventilation parameters on the infection potential of COVID-19 in a metro wagon is numerically studied. Two key indicators are used to quantify this potential. Based on the numerical results a regression analysis is performed to come up with the most suitable regression model for these key parameters. The proposed regression models are helpful in quantifying the infection
Comparative Study of Nusselt Number Correlations for Hitec Molten Salt
Molten salt has been realized as a potential candidate as a clean non-pollutant heat transfer fluid for concentrated solar power plants because of its high heat capacity and broad ranges of operational temperatures. In this study, the Nusselt number of the commercially known Hitec molten salt is numerically assessed, using k-ϵ model turbulence model with non-equilibrium wall functions, for the
Design of a Schlieren System for Visualization of Heat and Mass Transfer
In this contribution, a simple yet effective design for Schlieren photography system is described and implemented. The proposed system is used in the visualization of both heat and mass transfer phenomena. Refractive index gradient is created by a lighter to study mass transfer, then the lighter is ignited to create temperature gradient. Results show the ability of the proposed system in capturing
