| dc.description.abstract | Solar radiation, being the most widely distributed energy source, can be exploited using photovoltaic and solar thermal technologies. Due to its diversified area of applications the later one has got a great deal of attention leading to a well-established groups of conversion devices. Amongst them flat plate collectors are widely used in low to moderate temperature applications like domestic water heating, space heating, crop drying etc. Solar water heating systems, usually powered by flat plate collectors, have gained global popularity recently because better economic viability than the electrical heating devices. They are proved to produce hot water of up to 100°C above ambient temperature depending upon the season, location, solar intensity and collector design. Attempts had been made to improve the thermal performance of conventional solar flat plate collectors by providing various design and flow arrangements. The consequential limitation of the flat plate solar water collectors is the imperfect contact between the absorbing surface and fluid transport pipe. So, providing enhanced contact is one of the mechanisms at the top of the list of performance improvement. In this thesis work an attempt has been made to experimentally and numerically analyze a newly designed corrugated plate solar collector characterized by its chevron corrugated (sinusoidally profiled) absorber surface and there by an improved thermal contact. The numerical simulation of the collector has been performed by means of the Finite Volume Method (FVM) using commercial ANSYS Fluent 18.1 software. Both the numerical and experimental results revealed that the sinusoidal corrugation provides increased bond conductance leading to an increased outlet temperature and reduced plate to fluid temperature difference and there by an enhanced efficiency of the collector by . The experimental and numerical results of collector outlet temperature and collector efficiency appeared to be in a good agreement with a maximum deviation of about and for collector efficiency and water outlet temperature respectively. | en_US |
