Beginning by studying the time variation of the evolution of inviscid accretion discs around black holes, and their properties, the author investigates the change of the pattern of the flows when the strength of the shear viscosity is varied and cooling is introduced. He succeeds to verify theoretical predictions of the so called Two Component Advective Flow (TCAF) solution of the accretion problem onto black holes through numerical simulations under different input parameters. TCAF solutions are found to be stable. And thus explanations of spectral and timing properties (including Quasi-Period Oscillations, QPOs) of galactic and extra-galactic black holes based on shocked TCAF models appear to have a firm foundation.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053AstrophysicsMathematical physicsComputer scienceMathematicsAstrophysics and Astroparticleshttps://scigraph.springernature.com/ontologies/product-market-codes/P22022Theoretical, Mathematical and Computational Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19005Computational Mathematics and Numerical Analysishttps://scigraph.springernature.com/ontologies/product-market-codes/M1400XAstrophysics.Mathematical physics.Computer scienceMathematics.Astrophysics and Astroparticles.Theoretical, Mathematical and Computational Physics.Computational Mathematics and Numerical Analysis.523.8875015118Giri Kinsukauthttp://id.loc.gov/vocabulary/relators/aut792328BOOK9910300409603321Numerical Simulation of Viscous Shocked Accretion Flows Around Black Holes1771650UNINA
