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…

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…
