Sensor positioning and real-time estimation of non-observable fields is an open question in the nuclear sector, especially for advanced reactors. In Circulating Fuel Reactors (CFR), liquid fuel coolant are homogeneously mixed, thus these reactors will not have internal structures, making sensor primary circuit, including core, unresolved problem, most core blind to sensors. Thus, possibility estimating system state whole domain using a few local measurements has important implications...
Due to the multiple physics involved and their mutual complex interactions, nuclear engineers researchers are constantly working on developing highly accurate Multi-Physics models, focusing in particular core coupling of Neutronics Thermal-Hydraulics. Nevertheless, development stable models remains a challenging task despite advancements computational hardware software. This work investigates possibility combining available mathematical model with data collected physical systems, two-fold...
Compared to conventional engineering systems, nuclear reactors present unique physical and safety features that make their high-fidelity modelling both necessary complex. Indeed, is intrinsically a multi-scale multi-physics task. Up recent years, the approach for saw use of highly performing computer codes hardware retrieve model as close possible reality; whereas this remains true, especially from point view regulators assessments, an alternative has appeared in reactor world. models are...
Magnetohydrodynamics (MHD) investigates the intricate relationship between electromagnetism and fluid dynamics, offering a complete insight into behavior of conducting fluids under influence magnetic fields. This theory plays pivotal role in framework confinement fusion, where it can be applied to describe both thermonuclear plasmas confined inside vacuum vessel operating fluids, such as liquid metals molten salts, flowing within blanket future tokamaks. Currently, state-of-the-art numerical...
Hybrid Data Assimilation (HDA) methods are a class of numerical that aim at integrating Model Order Reduction (MOR) techniques into (DA) framework, thus combining mathematical models and experimental data. The objective is to reduce the solution time using MOR algorithms whilst keeping accuracy desired level observations, which serve as an update priori prediction model. This two-part work investigated HDA by applying them two classes problems: benchmark cases (part 1) facilities 2). In...
Hybrid Data Assimilation (HDA) methods aim at combining the advantages of mathematical models and experimental observations by integrating Model Order Reduction techniques into a framework, thus reducing solution time whilst keeping accuracy to desired level. HDA provide tools able estimate state system assuming have measurements available per each field describing (e.g., neutron flux, temperature, velocity, …). However, it is not always possible measure every interest for various reasons,...
Nowadays, interest in combining mathematical knowledge about phenomena and data from the physical system is growing. Past research was devoted to developing so-called high-fidelity models, intending make them able catch most of occurring system. Nevertheless, models will always be affected by uncertainties related, for example, parameters inevitably limited underlying simplifying hypotheses on, geometry equations; thus, a way, there exists an upper threshold model performance. Now, many...
As first proposed by Madelung in 1926, the analogy between quantum mechanics and hydrodynamics has been known for a long time; however, its potentialities possibility of using characteristic equations to simulate behavior inviscid fluids have not thoroughly investigated past. In this methodology, incompressible Euler are thus substituted Schrödinger equation, turning quasi-linear Partial Differential Equation into linear one, an algorithm literature as Incompressible Flow. Previous works on...
