Abstract: In this paper some results concerning the effect of turbulence model variation onto flame propagation in a particular combustion chamber with four tilted valves were elucidated. Flame propagation was represented by the evolution of spatial distribution of temperature in various cut-planes within combustion chamber while the flame front location was determined by dint of zones with maximum temperature gradient. The results presented are only a small part of broader on-going research activity in the field of multidimensional modeling of reactive flows in combustion chambers with complicated geometries encompassing various models of turbulence, different fuels and combustion models. The effect of turbulence model variation was analyzed through comparison of results of flame propagation obtained with eddy-viscosity model i.e. standard k-ε model of turbulence and results obtained with k- ξ-f model of turbulence. In the case of combustion all differences ensuing from turbulence model variati

Abstract: Every community and society has a very precious heritage which has to be and can be transferred to the next generation and it is the responsibility of the civil society to transfer that heritage to the next generation . The process of preserving and, reconstructing historical buildings poses several specific questions and raises problems which must be solved in the planning and management stage of the building process - from questions of architectural and arthistorical significance , via the future purpose of use of the building, links to the surrounding buildings, environmental questions, questions of cost, time analysis, and quality assurance problems. Many of these problems can be solved with the help of a detailed architectural plans, elevations and sections of the historical buildings and monuments which was created by an expert team .
