    The numerical methods and software for numerical modelling of the two-phase turbulent flows in the canals, sprays and interaction of the sprays with obstacles have been developed. To solve the obtained equation systems the finite-difference methods including ones developed by an author are applied. The task about concrete spraying (application of additive refractory cover) of the walls in the steel-smelting converters has been solved firstly in the accurate formulation. On base of the numerical modelling results the recommendations on the improvement of the concrete spraying process the introduction of which gives the sufficient economic effect have been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

    City transport causes the biggest part of road transport emissions. Besides, by engaging mainly fossil fuels in the city transport, we are responsible for air pollution in urban areas. On the other hand, passengers transport (private and public, individual and mass) may contribute substantially to reduce the negative impact on the environment by application of alternative fuels and declining of the use of fossil fuels. The main alternative fuels for drive systems in transport are the following: electricity, hydrogen, and biofuels. Synthetic fuels are option as a technology. Some of them are very effective but too expensive technologies. Another way is introduction of flexible transport (from door to door, on demand, etc.) which application enables to decrease the number of cars in urban centers to avoid congestions and the negative impact on the environment. This paper points out that public transport has a special role in the process of decreasing fossil fuel dependence, and the necessity for rapid alternative technology implementation, as well as development of the public transport system itself. Proposed is the introduction of public passenger transport from door to door that offers a comfort comparable to personal cars (specifically for handicapped persons) and helps to lowering congestions on the roads
