HYBRID POLYESTER COMPOSITES REINFORCED WITH SUNN HEMP AND FLAX FIBRES: SHORE D HARDNESS AND DIMENSIONAL STABILITY ANALYSIS Naveen Krishna V, Sivasankaran R, Srinivasa Daya Prasad, Govardhanan M S Transactions of Famena, 2025 Fibres are incorporated into polymeric matrix materials such as polyesters and epoxies to enhance the overall mechanical properties and open up a new range of applications in engineering. Natural fibres are recognized as alternatives to synthetic fibres due to their properties of being environmentally friendly, renewable, and lightweight. The aim of this paper is to experimentally determine the Shore D hardness and dimensional stability of polyester composites reinforced with sunn hemp and flax fibres. The water, oil, and acid absorption tests conducted on this composite (10 days) showed the maximum water, oil, and acid absorption levels of 13.4 %, 5.7 %, and 5.5 %, respectively.
Photovoltaic Module with Uniform Water Flow on Top Surface M. S. Govardhanan, G. Kumaraguruparan, M. Kameswari, R. Saravanan, M. Vivar, K. Srithar International Journal of Photoenergy, 2020 Though the solar photovoltaic (PV) module is used for power production, it usually works at high temperatures, decreasing its efficiency and therefore its output. So if an effective cooling method is to be implemented, it would reduce the heat from the solar PV module and increase its power production. Significant research in water cooling on both top and bottom surfaces of the PV module widen the scope for uniform cooling with constant module temperature throughout at any instant. In this work, uniform flow is maintained by means of overflow water from a tank fitted on the top of the PV module. Experiments were carried out with and without cooling. Performance parameters in terms of power output and efficiency have been presented for the PV module without cooling and cooling with three different mass flow rates. The results show that there is a significant rise in efficiency of the PV module by reducing its temperature. An accelerated output power of 23 W has been observed for a higher mass flow rate of 5.3 kg/min which is 15% higher than the photovoltaic module operating without cooling. Results were compared with previous researchers’ work and found to be a good enhancement. Theoretical results agree well with experiments.
