Modeling spectral and total solar irradiance variability from any vantage point in the Solar System
(2024-12-17)The Sun is the primary external energy source for all planets in the Solar System. Its radiative flux, known as solar irradiance, plays a crucial role in planetary atmosphere modeling. Accurate spectral solar irradiance ... -
Physical modeling of motile and sedimenting plankton: from simple flows to turbulence
(2022-11-22)Planktonic microorganisms play a fundamental role in oceanic ecology and chemical cycles. Different planktonic species are found at various levels of the oceanic trophic chain, ranging from photosynthetic organisms to ... -
Thermal Convection: Differential heating, travelling thermal waves and turbulent superstructures
(2022-05-30)Turbulent thermal convection is ubiquitous in geophysical, astrophysical, and industrial applications. In the present work, various phenomena in the convective paradigm systems of horizontal convection and Rayleigh-Bénard ... -
Experimental investigation of a sheared thermally unstable boundary layer
(2021-07-02)In many natural and industrial systems, heat is transported by mixed convection, where an externally driven flow causes advection of the temperature field in addition to the fluid motion due to buoyancy of differentially ... -
Superstructures, heat and momentum transport in inclined turbulent thermal convection of low-Prandtl-number fluids
(2020-09-24)Recent experiments by Vasil’ev et al. (2015a) using liquid sodium as working fluid inside an extremely slender Rayleigh-Bénard convection (RBC) cell of the diameter-to-height aspect ratio Γ = 1/20, which was inclined ... -
Studies of the radial gradient of rotation near the solar surface
(2018-02-16)Continuous observations of solar oscillations over the last twenty years have provided an opportunity to investigate interior properties of the Sun and their variations over the last two solar cycles. In this thesis, I ...
