Numerical simulation of thermal buoyant wall jets
(2013 , Conference Paper)
The main focus of this study is on the near field flow and mixing characteristics of the thermal
wall jets. A numerical study of the buoyant wall jets discharged from submerged outfalls from cooling
systems of power ...
An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference Paper)
In this study, a new finite volume method is developed for shallow water equations on a rotating
frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or
numerical damping for ...
Experimental Investigation on the Flexural Capacity of Reinforced Concrete Beams with Treated Wastewater and Recycled Concrete Aggregates
(
Qatar University Press
, 2023 , Conference Paper)
Eco-friendly concrete is the most recommended sustainable option to reduce the excessive diminution of concrete natural resources and the high generation of greenhouse gas emissions. Therefore, the present study explores ...
Telecommunication-wavelength lasing in er-doped gan multiple quantum wells at room temperature
(
OSA - The Optical Society
, 2018 , Conference Paper)
We report the realization of room-temperature, stimulated-emission in Er-doped-GaN multiple-quantum-wells at the 1.5-µm. Structures were grown by MOCVD and lasing was confirmed by threshold-behaviors of emission-intensity ...
Optimum Design of Plane Trusses Using Mathematical and Metaheuristic Algorithms on a Spreadsheet
(
Qatar University Press
, 2023 , Conference Paper)
Mathematical optimization refers to the process of finding the values of variables that maximize or minimize a function. Structural optimization is the process of designing a structure in such a way as to minimize its ...
Blockchain and its Potential in the Digitization of Land and Real Estate Property Records
(
Qatar University Press
, 2023 , Conference Paper)
A blockchain, is a decentralized digital ledger that is distributed across multiple computers, recording transactions in a way that cannot be altered without the consent of the network and the alteration of all subsequent ...
Preliminary Study on the Use of Reclaimed Asphalt in Public Works Authority Road Projects in the State of Qatar
(
Qatar University Press
, 2023 , Conference Paper)
This paper describes the outcomes of a preliminary study focused on the evaluation of four full-scale pavement sections in which reclaimed asphalt (RAP) was used in partial substitution of virgin aggregates during the ...
Development of a Comprehensive Pavement Design System for Roads in Wind and Solar Farms
(
Qatar University Press
, 2023 , Conference Paper)
This paper briefly, illustrates the structure and contents of an ongoing research program aimed at developing a set of procedures and tools to be used for the design of pavements in renewable energy projects and mainly in ...
Enhancing the Bond Durability of Basalt Fiber Reinforced Polymer Bars Using Basalt-Macro Fiber Reinforced Concrete
(
Qatar University Press
, 2023 , Conference Paper)
This paper presents a study about the bond durability of basalt fiber reinforced polymers (BFRP) bars embedded in concrete incorporating basalt macro fibers (BMF) when conditioned in harsh saline environment at 60 °C. A ...
Synthesis of Calcium Nitrate Self-Healing Microcapsules Using Aerosol OT Hexane Solution for Cementitious Materials
(
Qatar University Press
, 2023 , Conference Paper)
Calcium nitrate synthesis of in urea-formaldehyde shell has recently been used to produce self-healing microcapsules for construction applications. The original synthesis was based on water-in-oil emulsion with sulfonic ...
