Principles Of Enhanced Heat Transfer

Buildings are among the largest consumers of electricity in the US. A significant portion of this energy use in buildings can be attributed to HVAC systems used to maintain comfort for occupants. In most cases these building HVAC systems run on fixed schedules and do not employ any fine grained control based on detailed occupancy information. In this paper we present the design and implementation of a presence sensor platform that can be used for accurate occupancy detection at the level of individual offices. Our presence sensor is low-cost, wireless, and incrementally deployable within existing buildings. Using a pilot deployment of our system across ten offices over a two week period we identify significant opportunities for energy savings due to periods of vacancy. Our energy measurements show that our presence node has an estimated battery lifetime of over five years, while detecting occupancy accurately. Furthermore, using a building simulation framework and the occupancy information from our testbed, we show potential energy savings from 10% to 15% using our system.

Biodiesel is a recognized replacement for diesel fuel in compressed ignition engines due to its significant environmental benefits. The purpose of this study is to investigate the engine performance and emissions produced from Jatropha curcas, Ceiba pentandra and Calophyllum inophyllum biodiesel in compressed ignition engine. The biodiesel production process and properties are discussed and a comparison of the three biodiesels as well as diesel fuel is undertaken. After that, engine performance and emissions testing was conducted using biodiesel blends 10%, 20%, 30% and 50% in a diesel engine at full throttle load. The engine performance shows that those biodiesel blends are suitable for use in diesel engines. A 10% biodiesel blend shows the best engine performance in terms of engine torque, engine power, fuel consumption and brake thermal efficiency among the all blending ratios for the three biodiesel blends. Biodiesel blends have also shown a significant reduction in CO2, CO and smoke opacity with a slight increase in NOx emissions.

There has been significant increase in the use of composites materials as structural materials in most of the engineering applications. Here we have used Lapox 12 epoxy resin and K6 hardener as matrix, then polypropylene bags as reinforcement and Titanium dioxide and aluminum dioxide as filler materials. We made five samples of composite materials with different proportions of filler materials and tests including tensile test, flexural test, wear test, Rockwell hardness test and izod impact test are done to determine different mechanical features of the composite materials. The aim of this project is to examine the mechanical features and sliding wear performance of poly propylene reinforced epoxy composites with filler materials. Hand layup technique is used for the manufacturing of specimen and a 30 cm x 30cm x 0.3cm specimen is made and after that it is cutted in to required shapes and sizes as per ASTM standards. The test result of all specimen are tabulated and analyzed. The results revealed that the specimen with Titanium dioxide shows excellent mechanical properties than specimen with aluminum oxide and specimen without filler materials.
