Pseudo-boiling wall-bounded turbulence in supercritical flows: direct numerical simulation & flow physics
(English) This thesis presents the development and application of a high-fidelity computational framework for the direct numerical simulation (DNS) of high-pressure transcritical turbulent flows. These flows, characterized by strong thermophysical property variations in the vicinity of the pseudo-boiling region, exhibi...

Interface-resolved simulations of boiling heat transfer
Boiling heat transfer underpins many applications where large heat fluxes must be dissipated. Boiling is characterized by a wide range of coupled multiscale transport phenomena, making its accurate numerical prediction a long-standing challenge. In this context, interface-resolved simulation approaches - where the liqu...

Numerical Simulation of Solid Melting with Natural Convection Using the Double Lattice Boltzmann Method
A double lattice Boltzmann method (LBM) based on the D2Q9 model was developed to simulate natural convection melting and heat transfer in energy systems, including nuclear systems. Fluid flow in the liquid region was solved using the multi-relaxation-time LBM (MRT-LBM), whereas the energy equation was treated with the...

A CFD–Regression Surrogate Framework for Thermohydraulic Modeling of a Novel Plate Heat Exchanger
Plate heat exchangers are widely used in compact thermal systems, where heat-transfer enhancement must be balanced against hydraulic losses. This study develops a computational fluid dynamics (CFD) and regression-based surrogate framework for a novel plate heat exchanger (NPHE) under two working-fluid regimes. Three-di...

TURBULENT HEAT TRANSFER IN LATTICE-STRUCTURED MATRIX COOLING CHANNELS
Matrix cooling is an internal cooling concept for gas turbine blades that combines structural reinforcement with enhanced heat transfer through a rib-crossing lattice geometry. The repeated flow redirection generates strong shear layers, impingement, and vortical structures that significantly influence turbulent tran...
