Документ New design of the tractor exhaust muffler based on computational fluid dynamics analysis(НТУ "ХПИ", 2013) Samoilenko, D. E.New regulations and standards for noise emission increasingly compel the automotive firms to make some improvements in exhaust systems of engines which include the muffler. First of all such improvement concerns the decreasing of engine noise. Nowadays, the perforated reactive mufflers which have an effective damping capability are specifically used for this purpose. New designs should be analyzed with respect to both acoustics and back pressure. In this study, a new design of reactive perforated mufflers are investigated numerically by using computational fluid dynamics (CFD) tools. Back pressure was obtained based on the flow field analysis and compared for commercial and new design mufflers.Документ The problems of utilization of flare gases in internal combustion engines(НТУ "ХПИ", 2013) Marchenko, A. P.; Samoilenko, D. E.; Hamzah, Omar AdelThe problem of flare gases utilization in internal combustion engines is considered. Flaring associated gas from oil drilling sites is the most promising fuel for such purpose. Also the problems of detonation arising during the operation of internal combustion engines on flare gases are also studied. It is shown that the only independent parameter that affects the occurrence of detonation during operation of a gas engine is methane number which is a physical characteristic of the gas. The new conception of the internal combustion engine with on-board steam reformer to avoid the problem of detonation is offered in present study.
