The paper reports on the set up of an experimental protocol for the investigation of high temperature (1200 degrees C < T < 2200 degrees C) graphite combustion in supersonic flow conditions. Cylindrical graphite specimens (3 mm D, 100 mm L) are exposed to supersonic flow of nitrogen/oxygen mixtures in a small Planetary Entry Simulator, equipped with a plasma torch. The impact of the gas flow on the specimen determines a very sharp temperature rise. A fast IR camera allows to realize two-dimensional maps of the specimen temperature throughout the experiment. IR thermal images can also be of help to rebuild the consumption of the graphite rod. Results are checked against the sample weight loss and used to estimate the rate of carbon combustion as a function of temperature and reaction time. (C) 2013 Elsevier Inc. All rights reserved.

Analysis of the Heat Capacity for Pure CH4 and CH4/CCl4 on Graphite Near the Melting Point and Calculation of the T-X Phase Diagram for(CH3)CCl3+CCl4
Yurtseven, Hasan Hamit (2016-06-15)
We study the temperature dependence of the heat capacity C-p for the pure CH4 and the coadsorbed CH4/CCl4 on graphite near the melting point. The heat capacity peaks are analyzed using the experimental data from the literature by means of the power-law formula. The critical exponents for the heat capacity are deduced below and above the melting point for CH4 (T-m = 104.8 K) and CH4/CCl4 (T-m = 99.2 K). Our exponent values are larger as compared with the predicted values of some theoretical models exhibiting...
Evaluation of nusselt number for a flow in a microtube with constant heat flux including axial conduction, viscous dissipation and second-order slip model
Çetin, Barbaros; Bayer, Özgür (2010-09-28)
In this paper, the fully-developed temperature profile and corresponding Nusselt value is determined analytically for a gaseous flow in a microtube with a thermal boundary condition of constant wall heat flux. The flow assumed to be laminar, and hydrodynamically and thermally fully developed. The fluid is assumed to be constant property and incompressible. The effect of rarefaction, viscous dissipation and axial conduction, which are important at the microscale, are i...
Set up of an experimental apparatus for the study of fragmentation of solid fuels upon severe heating
Senneca, O.; Allouis, Christophe Gerard; Chirone, R.; Russo, S. (2010-04-01)
An experimental apparatus has been developed in order to perform tests of primary fragmentation of solid fuels under severe heating conditions. The device is a modified heated strip reactor, capable to reach 2000 degrees C in less than 0.2 s. Particles are laid on the strip and pyrolysed under inert or moderately oxidizing conditions. The char particles and their fragments, generated upon pyrolysis, can be recovered and analysed to assess the fragmentation propensity of the fuel.
Analysis of Transient Laminar Forced Convection of Nanofluids in Circular Channels
Sert, İsmail Ozan; Sezer Uzol, Nilay; Güvenç Yazıcıoğlu, Almıla; Kakaç, Sadık (2012-11-15)
In this study, forced convection heat transfer Characteristics of nanofluids are investigated by numerical analysis of incompressible transient laminar flow in a circular duct under step change in wall temperature and wall heat flux. The thermal responses of the system are obtained by solving energy equation under both transient and steady-state conditions for hydrodynamically fully developed flow. In the analyses, temperature dependent thermo-physical properties are also considered. In the numerical analys...
