Numerical Investigation of Macro Flow Dynamics of Downburst Wind Over Buildings and the Interference Effect
Abstract: A “Downburst” is an important weather phenomenon in which an air mass comes down with high velocity towards the ground from the cloud level during a Thunderstorm. Thunderstorms occur frequently in the eastern and Northeastern part of India. Thunderstorms over the Gangetic West Bengal and Assam are popularly known as ‘Kalbaishakhi’ and ‘Bardoisila’, respectively. Severe thunderstorms are known to cause detrimental impact on various facets of national activity like civil …

Analytical Solution to Bi-Linear Spring Mass Systems Free Vibration
Abstract: Dynamic systems are generally categorized as linear and non-linear systems based on the analysis approaches developed. Bi-linear spring mass systems form an intermediate category which possesses characteristics of both linear and non-linear systems. Analytical solutions to bi-linear systems cannot in general be reduced to a single equation covering the entire motion domain as in the case of linear systems. Nevertheless, the step-wise linear solutions can be obtained within each domain …

Comparative Study of Oxidation and Hot Corrosion Behavior of Uncoated and Detonation Gun Sprayed Cr3C2-25NiCr Coating on SA516 Boiler Steel at 800°C
Abstract: In the present investigation Cr3C2-25NiCr powder was deposited on boiler steel SA 516 (Grade 70) by detonation gun process. The oxidation and hot corrosion performance of coated as well as bare boiler steel was studying in the air and aggressive environment of Na2SO4–50% NaCl under cyclic conditions at an elevated temperature of 8000C. Oxidation and hot corrosion of metals and alloys has been recognized as a serious problem for elevated-temperature …

A Comparative Study on Evolutionary Algorithms to perform Isogeometric Topology Optimisation of Continuum Structures using Parallel Computing
Abstract: The optimization of computational performance along with the topology optimization of structures is the main focus of this study. The computational performance of the program is enhanced using two search engines in parallel. The search process is done using a least pop size which has reduced the number of computations required to optimize the objective function. The geometry can be exactly represented using isogeometric basis functions where the same basis …
