        Relation of change in geometrical parameters in the thermal performance of solar chimney

        Biranchi Narayana Padhi,Mukundjee Pandey,Ipsita Mishra 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.10

        The article deals with the effects of change in dimensions of solar chimney upon the thermodynamic characteristics of the air flowing inside it. The solar chimney at Manzanares (Spain) has been selected as the base model for this study. ANSYS-Discovery-Aim 2019 R1 has been used for the simulation of different geometric variations of solar chimney along with its validation with the work by Haaf et al. It is found that of all the geometric changes, the increase in roof height is undesirable. While for others like increase in chimney height, increase in chimney diameter and increase in collector radius gives desirable results in terms of increase in velocity of air. Also, for the case with an increase in chimney diameters; it is found to be suitable if the turbines are placed at the outlet of the collector and not within the chimney.
