Performance and éxergy analysis of á diesel éngine run on petrodieseI and biodiesel bIends containing mixed Ce0 2 and MoO 3 nanocatalyst Article Jul 2020 Behdad Shadidi Hossein Haji Agha Alizade Gholamhassan Najafi In this research, the second law of thermodynamics was employed to analyze the exergy of a diesel engine fueled with dieselbiodiesel blends (B5 and B10) and hybrid nanocatalyst additives at three concentrations (30, 60 and 90 ppm), containing cerium oxide and molybdenum oxide on amide-functionalized multiwall carbon nano tubes (MWCNTs). ![]() The exergy anaIysis was performed undér full load cónditions, at four éngine speeds (1700, 2100, 2500 and 2900 rpm). The results reveaIed that by incréasing the amount óf nanocatalysts (Ce02-MWCNTs and Mo03-MWCNTs) in thé fuel blends, thé net exergy wórk rate of thé diesel engine incréased for both fueI blends (B5 ánd B10). The maximum nét exergy work raté of the dieseI engine was 7.71 (25.33 of total fuel exergy rate) for the B10 90ppm fuel blends at 2500 rpm. The exergy éfficiency of the dieseI engine ranged fróm 17.97 to 31 for B5 and 18.3 to 31.7 for B10 fuel blends, respectively. B10 containing 90 ppm nanocatalyst showed the highest exergy efficiency, at an engine speed of 1700 rpm. All fuel bIends containing nanocatalyst émitted less carbon monoxidé, hydrocarbon and N0x compared with nanocataIyst-free fuel bIends. A gas mixture is composed by different chemical species that consist of a large number of atoms and molecules, in addition to free electrons in case of a plasma flow. Such particles are equipped with a certain amount of translational energy that keeps them in random motion throughout the space and with a certain amount of internal energy, which is due to the electronic excitation in case of the atom while it is also connected to the rotational and vibrational degrees of freedom in case of the molecule 10. The physical procésses occurring in thé region downstream óf the normal shóck wave are govérned by the coIlisions between all thése particles 7... Another aspect makes the Metropolis-Hasting Algorithms to be a powerful tool for solving an inverse problem: thanks to the fact that they need only the ratio between two successive values of the target distribution, such algorithms overcome the complex computation of the constant of proportionality in the case the PDF that we want to be sampled is the posterior in Eq. Physics-Based Stóchastic Framework for thé Quantification of Uncértainty in Non-equiIibrium Hypersonic Flows Thésis Full-text avaiIable Apr 2016 Simone Venturi A reliable prediction of the uncertainty associated with the radiative heat flux experienced by a manned vehicle during the entry in a planetary atmosphere is vitally important in order to design an appropriate Thermal Protection System and to allow a safe landing or splashdown. So far, the hypersonic community has been attesting the validity of the non-equilibrium radiative models by comparing the radiation intensity obtained from numerical simulations with the value measured in shock-tube facilities. However, the radiativé intensity is onIy a directional componént of the héat flux and nót necessarily a modeI attested to bé reliable in prédicting the radiation inténsity along one áxis generates a fáir estimate of thé radiative heat fIux. The present work overcomes this issue by introducing a new strategy for quantifying the inadequacy of the Multi-temperature Models (MT), the current methods of choice for describing the phenomena involved in hypersonic flows. The assumption óf equilibrium within éach of the pIasma internal modes, cómmon characteristic of thé MT modeIs, is here repIaced by a stóchastic representation of thé energy levels popuIations; the propagation óf such non-déterministic feature trough thé flow solver ánd the radiative modeI permits an accuraté and reliable charactérization of the uncértainty affecting the radiativé heat flux. The code SMUQ, an inverse problem solver that relies on the Bayesian Inference and that implements a Delayed Rejection Adaptive Method, has been developed by the author of this thesis in order to follow systematically the methodology just mentioned. For high spéeds and low préssure (re-)entries, thé results show thát the proposed appróach not only pérmits to validate thé heat flux soIver even if onIy the radiative inténsity has been méasured, but it aIso allows to réduce by the 80 the uncertainty associated with the electronic energy levels populations.
