Abstract: A solar receiver system has been designed installed and tested under real conditions in the faculty of Engineering, Tula’s Institute, Dehradun. The system consists of a heliostats with a solar central receiver. The function of this arrangement is to heat the basin water in order to increase temperature and pressure thus increase the solar still productivity. The influence of coupling the heliostats with the solar central receiver is reported, especially concerning distilled water productivity. A simple transient mathematical model is presented. The model is based on analytical solution of the energy-balance equations for different parts of the model. Numerical calculations ave een arrie ut r li ati e ra un n iti ns latitu e, E longitude). It is observed that the use of the proposed solar desalination system is to improve the accumulative productivity of arrangement by up to 90% when using 28 heliostats in three circle.

Abstract: Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight. Such concrete can be used for casting heavily reinforced sections at places where there can be no access to vibrators for compaction and in complex shapes of formwork which may otherwise be impossible to cast, giving a far superior surface than conventional concrete. Various approaches for designing the mix composition of SCC have been published worldwide, however each has its own suitability and limitations. Earlier methods e.g. Ojawa, LCPC, Hwang etc. are more or less specific to certain conditions and materials. In this study, a new generalized method for Mix Design Of SCC, suitable for Indian construction conditions, is proposed and a QT Creator Based Software is developed on the basis of generalized formulated equations. QT Creator is a cross-platform C++ integrated development environment, which is used to make a user interface software for SCC mix design. The proposed m
