Opis:: Some recent advances in computational gas dynamics of exhaust diffusers are presented. The compressor/turbine axial-radial exhaust diffusers and outlet devices of compressor/turbine units, exhaust hoods for power steam turbines are considered. The peculiarities of gas dynamics of the above mentioned devices are discussed. The formulations of problems for CFD analysis of these devices are discussed including the coupling procedure for joint operation of the last stage and exhaust hood. The numerical method and the implementation of a differential turbulence model are described. The new approach to the description of computational domain and parallel numerical solution of transport equations based on the unstructured set of structured grid blocks is also presented.

Opis:: The use of comfort systems, the number of which in vehicles is constantly increasing, has a direct impact on fuel consumption and engine load. As part of the article, the vehicle's drive in real operating conditions was analyzed in terms of the emission of toxic compounds. The tests were carried out without and with the systems turned on, using the PEMS apparatus, where road emissions of carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides and solid particles were measured in terms of mass, number and size distribution of diameters. The track was driven four times with different setting of the powertrain of examined car. The differences concerned the number of comfort systems in the vehicle and the mode of operation of the combustion engine.
