Abstract: Comparison of Comparison of Solar Power System (CSP) power plants will be introduced and discussed; Solar Tower (ST) plants and Parabolic Trough (PT) plants are subjects of this comparison. The comparison will be made possibly analytical or quantitatively instead of qualitatively. Examples will be presented and explained in detail. The main issues such efficiency, area of the plant, environmental issues, molten salt storage, the cost of the plants, dust and humidity, maintenance and operation cost and total investment are discussed.

Abstract: Dimples play a very important role in heat transfer enhancement of electronic cooling systems, heat exchangers etc. This work mainly deals with the experimental investigation of forced convection heat transfer over circular shaped dimples of different diameters on a flat copper plate under external laminar flow conditions. Experimental measurements on heat transfer characteristics of air (with various inlet flow rates) on a flat plate with dimples were conducted. From the obtained results, it was observed that the heat transfer coefficient and Nusselt number were high for the copper plate in which the diameter of dimples increases centrally in the direction of flow (case c) as compared to the other two cases.

Abstract: Phase-Change Materials (PCMs) are substances with a high heat of fusion that melt and solidifyat a certain temperature range. Theyare capable of storing and releasing large amounts of energy and have a high capacity of storing heat. PCMs preventenergy loss during material changes from solid to liquid or liquid to solid. They have several advantages such as its self-nucleating properties, and disadvantages such as having low thermal conductivity [4].There are different types of PCM with a wide range of applications. This paperstudies the potential application of PCMs in building as energy conservation materials.The analysis shows the result shows that the use of BioPCM materialas insulation layer in building can decrease the cooling load by 20% in comparison to standard one.

Abstract: A qualitative analysis for determining axis of a gas pipeline in view of general risk is outlined in the paper. The increasing building of gas pipelines for energy transportation vehicle, the importance of risk associated to this transport is gained strong importance. Risk assessment is an extremely useful tool in providing a framework in which to identify the possible hazards and determine the risks associated with gas pipelines. The determination of route, thickness, diameter and segment lengths is the major factor of constructing gas pipelines. The paper is presenting this risk in general and in a qualitative manner.
