A MODEL FOR PASTEURIZATION WITH MICROWAVES IN A TUBULAR FLOW REACTOR OZILGEN, S; OZILGEN, M (Elsevier BV, 1991-05-01) Thermal death kinetics of Escherichia coli with microwaves were studied by using a tubular flow reactor with different diameters, lengths, and flow rates. Mathematical models were presented for temperature profile development and death of the microorganisms along the reactor. A first-order kinetic expression in biomass concentration simulated the death phenomena. Temperature effects on the death rate constant were expressed with an Arrhenius expression. Numerical values of the constants of this expressi...
A SIMPLIFIED MODEL FOR VIBRATING MASS CONTROL MOMENT GYROSCOPE Akbulut, Burak; Arberkli, Ferhat; Azgın, Kıvanç; Tekinalp, Ozan (2017-02-09) A novel satellite attitude actuator based on vibrating masses was previously proposed. Its governing equations were obtained and simulated. In this study, the resulting mathematical model is validated via energy as well as the conservation of angular momentum methods. Additionally, the mathematical model for the complete system was too complicated for analysis. In this work, a representative simplified set of equations describing vibrating mass control moment gyroscope (vCMG) dynamics in high fidelity are a...
A novel approach to condensation modeling at the fin top of a grooved heat pipe Akdağ, Osman; Dursunkaya, Zafer; Department of Mechanical Engineering (2019) Phase-change passive heat spreaders have the capability of carrying large amounts of heat from a heat source to a heat sink creating a small temperature difference. One common type of the passive heat spreaders is the heat pipes. The liquid flow inside a heat pipe is driven by the capillary pressure gradient created by a wick structure on the inner wall, which may be in the form of grooves, sintered grains or wire meshes. In the literature, grooved heat pipes are the most studied ones for modeling and exper...
A possible radiative model for micronic carbonaceous particle sizing based on time-resolved laser-induced incandescence Allouis, Christophe Gerard; Rosano, F; Beretta, F; D'Alessio, A (2002-03-01) A numerical model of time-resolved laser-induced incandescence (TIRE-LII) for different kinds of large carbonaceous particle is developed in this paper. Theoretical temporal LII signals were computed for the following classes of particles: soot, the well known hollow particles called cenospheres (tens of microns) and full carbonaceous particles called by analogy pleospheres (a few microns), pleo- from the Greek pleos (solid). The large carbonaceous particles have a characteristic time for internal gradient ...
