Proposed 2MW Wind Turbine for Use in the Governorate of Dhofar at the Sultanate of Oman
Osama Ahmed Marzouk, Omar Rashid Hamdan Al Badi, Maadh Hamed Salman Al Rashdi +1
In this work, we propose a preliminary design of a horizontal-axis wind turbine (HAWT) as a candidate for the Dhofar Wind Farm project, in the southern Omani Governorate "Dhofar",…
Adiabatic Flame Temperatures for Oxy-Methane, Oxy-Hydrogen, Air-Methane, and Air-Hydrogen Stoichiometric Combustion using the NASA CEARUN Tool, GRI-Mech 3.0 Reaction Mechanism, and Cantera Python Package
Osama A. Marzouk
The Adiabatic Flame Temperature (AFT) in combustion represents the maximum attainable temperature at which the chemical energy in the reactant fuel is converted into sensible heat…
Construction of a Small-Scale Vacuum Generation System and Using It as an Educational Device to Demonstrate Features of the Vacuum
Osama A. Marzouk, Walid Ali Marjan Haje Rhaim Jul, Amjad Masoud Khalfan Al Jabri +1
We developed a vacuum generation system composed of a reciprocating compressor (3 tons of refrigeration) with an inverted-function that is ready to be hooked flexibly to a gas-tigh…
Effects of Turbulence Modeling and Parcel Approach on Dispersed Two-Phase Swirling Flow
Osama A. Marzouk, E. David Huckaby
Several numerical simulations of a co-axial particle-laden swirling air flow in a vertical circular pipe were performed. The air flow was modeled using the unsteady Favre-averaged…
Coupled differential-algebraic equations framework for modeling six-degree-of-freedom flight dynamics of asymmetric fixed-wing aircraft
Osama A. Marzouk
This study presents a comprehensive mathematical framework for modeling the flight dynamics of a six-degree-of-freedom fixed-wing aircraft as a rigid body with three control surfac…
New Weighted Sum of Gray Gases (WSGG) Models for Radiation Calculation in Carbon Capture Simulations: Evaluation and Different Implementation Techniques
Osama A. Marzouk, E. David Huckaby
We apply several weighted sum of gray gases models (WSGGMs) to calculate the radiative absorption coefficient for gas mixtures containing H2O and CO2. Our main objectives are to an…
Nongray EWB and WSGG Radiation Modeling in Oxy-Fuel Environments
Osama A. Marzouk, E. David Huckaby
According to a recent U.S. Greenhouse Gas Emissions Inventory (1), about 42% of 2008 CO (a greenhouse gas) emissions in the US were from burning fossil fuels (especially coal)…
A Flight-Mechanics Solver for Aircraft Inverse Simulations and Application to 3D Mirage-III Maneuver
Osama A. Marzouk
The main objective of this paper is to present a general mathematical model and an associated numerical algorithm applicable to an arbitrary fixed-wing fixed-mass aircraft undergoi…
Multi-Physics Mathematical Model for Weakly-Ionized Plasma Flows
Osama A. Marzouk
This work presents a multidisciplinary mathematical model, as a set of coupled governing equations and auxiliary relations describing the fluid-flow, thermal, and electric fields o…
A Nonlinear ODE System for the Unsteady Hydrodynamic Force -- A New Approach
Osama A. Marzouk
We propose a reduced-order model for the instantaneous hydrodynamic force on a cylinder. The model consists of a system of two ordinary differential equations (ODEs), which can be…
Changes in Fluctuation Waves in Coherent Airflow Structures with Input Perturbation
Osama A. Marzouk
We predict the development and propagation of the fluctuations in a perturbed ideally-expanded air jet. A non-propagating harmonic perturbation in the density, axial velocity, and…
Cantera-Based Python Computer Program for Solving Steam Power Cycles with Superheating
Osama A. Marzouk
One of the main sources of electricity generation is power plants that use water (steam) to rotate turbines, which drive large electric generators. The steam can be generated from…
In the Aftermath of Oil Prices Fall of 2014/2015-Socioeconomic Facts and Changes in the Public Policies in the Sultanate of Oman
