Abstract. Atmospheric black carbon (BC) is the strongest solar radiative absorber in atmosphere, exerting significant influences on earth's radiation budget. The mass absorption cross section (MAC) a crucial parameter for converting light coefficient (σab) to equivalent BC concentration (EBC). Traditional filter-based instruments, such as AE33, use constant MAC of 7.77 m2/g at 880 nm derive EBC...

Abstract In this paper, we propose a general method for solving structural mechanics problems by developing “functional model”. It is implemented defining the required geometrical and physical relationships in their form via analytical numerical functions. For that purpose, special programming language Calcpad used. The obtained data structure processed core engine, which generates computer cod...

The rotating flash flow has rarely been studied, although its characteristics affect significantly the performance of two-phase turbine. In this paper, through analyzing flashing obtained by CFD methods, which is validated with experimental data, relationships average parameters under various rotational speeds were studied theoretically and numerically using equations established on Frenet coor...
