(K.K.Wagh Institute of engineering education & research, 2019-06-08) Ansari, Zakir; Khan, Tabrez; Syed, Kaleem; Syed, Shariq
In institutes of higher education, record keeping and its retrieval has always been a problem. Often it is required that the same documents which originated from a common source are to be used by multiple users at different places for different purposes. This puts forward multiple challenges ranging from timely retrieval to data security. To overcome all such issues, a safe, secured,updated and efficient retrieval system is installed, configured and maintained at the institute level using open source cloud software called Own cloud. The user groups have been created program-wise. Then the user accounts are created for every faculty and added to specific program group. A directory structure has been created considering the common ministrative and teaching-learning requirements of the programs. This structure has been shared with all the faculty members of the respective program. A write access or read access is provided to all the concerned users through which each user has required access on fly. Every faculty user has 1 GB quota and department clerk has 10 GB quota, which can be used to store individual's teaching-learning and administrative records. Such implementation has provided an immediate and efficient access to all the teaching-learning and administrative records at any point of time and any location.
Experimental Investigation on Forced Convection Heat Transfer Augmentation Using Annular Blockages
(P and R Engineering Consultancy Publication, 2015-05) Herle, A
Abstract— Heat exchangers have several industrial and engineering applications. The design procedure of heat exchangers is quite complicated, as it needs exact analysis of heat transfer rate and pressure drop estimations apart from issues such as long-term performance and the economic aspect of the equipment. Whenever inserts are used for the heat transfer enhancement, along with the increase in the heat transfer rate, the pressure drop also increases. This increase in pressure drop increases the pumping cost. Therefore any augmentation device should optimize between the benefits due to the increased heat transfer coefficient and the higher cost involved because of the increased frictional losses. Experimental work on heat transfer augmentation using annular blockages. Inserts when placed in the path of the flow of the fluid, create a high degree of turbulence resulting in an increase in the heat transfer rate and the pressure drop. The work includes the determination of friction factor and heat transfer coefficient for various annular blockages and annular blockages having different diameter. The results of annular blockages having different diameter have been compared with the values for the plain tube. Four annular blockages (di=20%, 30%, 40% & 50% reduction in outer diameter) are used in the study.
