description

Bakalaura darbā uzmanība tiek pievērsta šķidrā metāla svina-litija (Pb-17Li) magnetohidrodinamiskas (MHD) plūsmas kustībai kvadrātveida nemagnētiska tērauda kanālā spēcīgā ārējā magnētiskajā laukā un tur notiekošajiem procesiem. Darba mērķis ir, izmantojot modelēšanas programmu ANSYS FLUENT, skaitliski izpētīt svina-litija MHD plūsmu, lietojot dažādus modeļus un tuvinājumus, un salīdzināt rezultātus uz eksperimentālajiem mērījumiem. Darbā apskatīti vienkāršoti analītiskie modeļi, veikti skaitliskie aprēķini un eksperiments. Analītisko aprēķinu precīzie atrisinājumi salīdzināti ar skaitliskajiem rezultātiem, galveno skaitlisko parametru ietekmes novērtēšanai. Iegūtie rezultāti izmantoti trīsdimensionālas problēmas skaitliskai risināšanai, kurai nav analītiska atrisinājuma. Skaitliskie rezultāti salīdzināti ar eksperimentālajiem datiem, veikta rezultātu analīze un interpretācija. Atslēgvārdi: MHD plūsma, svins-litijs, ārējais magnētiskais lauks, potenciālu starpība, spiediena kritums, skaitliskā modelēšana.
