Research Activities

·     Vehicle underhood aerothermal management

Development of measurement methods for experimental analyzes in the underhood, physical analysis of heat exchanges in the area comprising the engine and surrounding components and development of the associated analytical models, Analysis and thermal modeling of the area comprising the fan and the different ​​heat exchangers, Heat exchanger modeling and control.

 

·     Multifunctional heat exchangers/reactors

Static mixers and multifunctional heat exchangers/reactors (MHE/R) are being increasingly incorporated in process industries for their mixing and heat transfer capabilities. Process intensification is a chemical engineering purpose that consists in seeking processes with higher productivity, safer operating conditions, reduced waste production, and lower energy consumption. New applications are being explored and new on-line exchanger/reactor designs are being developed offering several advantages compared to batch processing and mechanically agitated vessels. The small space requirement, low equipment operation and maintenance costs, sharp residence time distribution, improved selectivity through intensified mixing and isothermal operation, byproduct reduction, and enhanced safety are the main features that have promoted the use of these devices in chemical, pharmaceutical, food processing, polymer synthesis, pulp and paper, paint and resin, water treatment, and petrochemical industries.

 

 

·     Experimental Fluid Mechanics

·         Experimental Investigation of belt skimmer performance in oil spill recovery

Viscous oil of controlled volume is to be poured on the water surface. Oil film thickness is to be measured using a graduated scale ruler or ultrasonic sensor, then compared with the calculated value. In order to keep the oil film thickness constant during the experiment, stored oil in the compensating tank is to be poured over the water surface through a manual control valve. Also belt material will be changed using the available material in the local market to investigate the effect of belt material on oil recovery rate. 

 

·         Effect of upstream installations on the accuracy of Ultrasonic flow meter

The aim of this project is to study experimentally the effect of upstream installations upon the accuracy of the ultrasonic flow meter. Correction factors are also obtained to substitute the error in the reading of ultrasonic flow meter.

·     Computational Fluid Dynamics (CFD)

·         Fluid-Structure Interaction (FSI)

Fluid-structure interaction is a complex multi-physics issue with contiguous domains consisting generally on viscous fluid flow over elastic solid structures. The elastic structure deforms due to fluid action; mainly pressure and viscous stress. The present project concerns the development of robust numerical solvers for fluid-structure interaction problems which is a fundamental issue in many engineering fields, such as heat exchangers and chemical reactors, marine cables and petroleum production risers, aeronautics, vortex induced vibration and noise, hemodynamics and blood vessel dynamics.

 

·         Magnetohydrodynamic flows (MHD)

The present project concerns the numerical simulations of an electrically conducting fluid driven by the Lorentz force resulting from an imposed external magnetic field normal to a potential difference. This research discipline, generally known as magnetohydrodynamic (MHD) flows, is in the interest of many engineering and physical applications such as plasma physics, thermo-nuclear fusion control, geophysics including oceanography and weather prediction and solid melting processes. This work is performed in parallel with experimental study carried on at the Physics Department of the American University of Beirut (AUB). The objective of this project is to provide a better understanding of the effect of electro-magnetic forcing on the vorticity generation in quasi-2D and 3D turbulence and to analyze the role of the coupling of large scales to small ones.
 
  

·         Vortices, turbulence and flow instability

This project concerns the study of flow instabilities which may be caused by spatial or temporal perturbation, or by a combination of both. Spatial perturbations are for example vortex generators, surface roughness, curves and concave surfaces… Moreover, an analysis on the interaction between small and large eddies is conducted to better understand quasi-2D and 3D turbulence.
