Mathematical Modeling of the NOTAR Antitorque System for Flight Simulation
Yavrucuk, İlkay; Uzol, Oğuz (2013-04-01)
In this paper, a mathematical model of a helicopter NO TAil Rotor (NOTAR) antitorque system is developed for real-time flight simulations. The model consists of the circulation control tail boom, direct jet thruster, and the vertical stabilizers. The airflow inside the tail boom is modeled by dividing the flow into aerodynamic control volumes. The model features a bladeelement-type approach for modeling the mass flow through the axial fan blades as well as aerodynamic mass and momentum conservation calculat...
Mathematical modeling and simulation of suspension droplet drying
Özcan, Ahmet Furkan; Uludağ, Yusuf; Department of Chemical Engineering (2019)
Drying procedures like spray drying, fluidized bed drying etc. are widespread industrial applications. Such procedures mainly aim to produce high value pharmaceuticals and bulk commodities such as dried milk and detergent powders, which require controlled physical properties that are dependent on the drying process that they are subject to. The aim of this study is to model the kinetics of water droplet drying containing nanosized SiO2 particles and simulate the coupled heat and mass transfer processes via ...
Mathematical modeling of nox emissions in bubbling fluidized bed combustors
Afacan, M. Onur; Selçuk, Nevin; Department of Chemical Engineering (2005)
A comprehensive model, previously developed and tested for prediction of behavior of continuous fluidized bed combustors is extended to incorporate NOx formation and reduction reactions and applied to the simulation of METU 0.3 MWt Atmospheric Bubbling Fluidized Bed Combustor (ABFBC) burning lignites with high volatile matter in their own ashes. The predictive accuracy of the model was assessed by comparing its predictions with measurements taken previously on the same rig. Favorable comparisons are obtaine...

Mathematical modeling of adsorption/desorption systems for chemical heat pumps
Yurtsever, Ahmet Onur; Uludağ, Yusuf; Karakaş, Gürkan; Department of Chemical Engineering (2011)
Despite their limited commercial applications, chemical heat pumps (CHP) have been considered as an important alternative to conventional heating and cooling technologies. In this study, the adsorption-desorption of ethanol over activated carbon was applied on the CHP reactor. The ethanol vapor - activated carbon adsorption rate was determined at 30, 60, 90 and 120° experimentally by using Intelligent Gravimetric Analyzer C(IGA). The experimental adsorption data were used on the transient modeling of reacto...
