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 ...
Design charts for combined chilled ceiling displacement ventilation system and personalized evaporative cooler.

Mirzaie, Sahar Jalil. (2012)

This work introduces operational energy-comfort design charts for a chilled ceiling (CC)-displacement ventilation (DV) system aided with personalized evaporative cooler (PEC) for typical office load of 70 W-m². The proposed ...
Determination of the evaporation coefficient of lubricating oil aerosols -

Jaber, Sara Said (2013)

Unburned engine lubricating oil (LO) accounts for a major fraction of the primary organic aerosol (POA) emissions of internal combustion engines. Because LO spans a wide volatility range, its gas-particle partitioning ...
DSMC investigation of the unsteady dynamics of a squeeze film beneath a microstructure undergoing large oscillations

Diab, Nadim Ali. (2013)

This dissertation investigates the behavior of a gas film in the vicinity of a micro RF switch. A two and three dimensional numerical study of the flow field is performed around a micro-cantilever beam that oscillates ...
Effect of wall conduction on natural convection heat transfer in attic spaces / by Alaa Hussein Abdel Samad.

Abdel Samad, Alaa Hussein. (2012)

In this study, steady natural convection heat transfer in trapezoidal enclosures is investigated numerically under winter-like and summer-like boundary conditions. These enclosures represent attic spaces with pitched roofs ...
Effective desiccant dehumidification system with two-stage evaporative cooling for hot and humid climates -

El Hourani, Mario George, (2013)

This study examines the design and operation of a hybrid air conditioning system that uses 100percent fresh air and integrates a solid desiccant dehumidification system with a two-stage evaporative cooling system to optimize ...
Evaluation of initial embodied energy, passive design strategies, and renewable energy systems for a detached house - by Ghaith Bashar Tibi.

Tibi, Ghaith Bashar. (2012)

Developed through holistic approach, this study aims at setting new applicable design guidelines for single-family detached residences in the Lebanese inland region. This thesis is an evaluation of the effects of using ...
Experimental study for operation of liquid desiccant system to supply space air conditioning and fresh water needs - by Anwar Rached Hassoun.

Hassoun, Anwar Rached. (2011)

This work presents an experimental study of the performance of a small-size solar-powered liquid desiccant system (LDS) that meets both space air conditioning and fresh water needs in Beirut humid climate. The experimental ...
Experiments on the heating and mechanical effects of high intensity focused ultrasound

Quraini, Moath Mustafa. (2012)

Free field experimental measurements of the temperature rise of water and tissue deformation in the focal region of a 2 MHz high intensity focused ultrasound (HIFU) transducer were performed. Millisecond pulsed HIFU was ...
Flexor tendon repair using sutures with different cross sectional areas -

Hantouche, Mireille Michel, (2013)

Tendon repair surgeries are critical and challenging since the repair site must be capable of sustaining passive and active immobilization forces with a configuration that would ensure the integrity of the tendon to ...
The flow dynamics about a cylindrical cactus plant model in cross wind

El Makdah, Adnan Milad. (2012)

Researchers were in many occasions inspired from the biology field in order to improve engineering systems. Cactus trees are long cylindrical plants with longitudinal grooves. They have survived the harsh dessert environment ...
Fresh air personalized ventilator systems for occupant-controlled microenvironment

Makhoul, Alain Hanna. (2013)

The project aims towards integrating more than one air distribution system by separating the fresh and recirculation air supply system in an effort to lower fresh air needs and to substantially reduce the air conditioning ...
Full scale-low computational cost virtual CFD model to predict the performance of a 10 ton roof-top AC unit / by Iyad Anwar Fayssal.

Fayssal, Iyad Anwar. (2012)

This thesis extends the work of Moukalled et al. [1] for predicting the performance of a roof-top air conditioning unit using CFD codes. Recently, Moukalled et al. [1] studied numerically the thermal and hydrodynamic ...
Gait generation for two link planar system in viscous environment

Babikian, Sevag Haroutioun. (2012)
