Abstract The study investigates the influence of erosion over leading edge S809 series airfoil and its impact on aerodynamic performance wind turbine blades. research work determines how affects blades at an angle attack varying from 0° to 45° for fixed Reynolds number 2.1 x 10 5 . To analyse flow characteristics, average pressure acting around surface is scanned with aid 20 taps. time 10,000 s...

Soil erosion is the most widespread form of soil degradation. Land area globally affected by erosion is 1094 million ha (Mha) by water erosion, of which 751 Mha is severely affected, and 549 Mha by wind erosion, of which 296 Mha is severely affected. Whereas the effects of erosion on productivity and non-point source pollution are widely recognized, those on the C dynamics and attendant emissio...

ABSTRACT The radial structure of debris discs can encode important information about their dynamical and collisional history. In this paper, we present a three-phase analytical model to analyse the evolution solids in discs, focusing on joint temporal dependence. Consistent with previous models, find that as largest planetesimals reach equilibrium inner regions, surface density dust becomes pro...

Eroded enamel is more susceptible to abrasive wear than sound enamel. New toothpastes utilizing diamond particles as abrasives have been developed. The present study investigated the abrasive wear of eroded enamel by three commercially available toothpastes (one containing diamond particles) and compared it to the respective wear of sound enamel caused by these toothpastes. Seventy-two bovine e...

Soils are an essential factor contributing to the agricultural production of rainfed crops such as barley and triticale cereals. Changing environmental conditions inadequate land management endangering soil quality productivity and, in turn, crop affected. Advances hyperspectral remote sensing great use for spatial characterization monitoring degradation status, well its impact on growth produc...
