Abstract:
Namen magistrskega dela je s pomočjo računalniških simulacij ugotoviti primernost uporabe UniPore celične strukture kot izmenjevalca toplote z analizo njenega toplotnega obnašanja pri različnih režimih obratovanja. Magistrsko delo zajema študij literature s področja obnašanja celičnih gradiv oz. poroznih snovi pri termičnih obremenitvah, pripravo numeričnih modelov celičnih struktur UniPore, ter izvedbo parametričnih računalniških simulacij prenosa toplote skozi UniPore celično strukturo, izdelano iz bakra pri enakih vhodnih temperaturah, za različna grelna medija (voda, zrak) in hitrostih toka tekočine vzdolž pore. Tokovni režim bo omejen na laminarni tok viskozne tekočine. Na osnovi simulacij podrobne geometrije je bilo potrebno izdelati tudi poenostavljen model toplotnega prenosnika z upoštevanjem koncepta porozne snovi. Rezultati računalniških simulacij so nam tako služili za opis hidrodinamskih lastnosti (tlačni padec) in toplotnih lastnosti (vrednost toplotne difuzivnosti porozne snovi ter Nusseltovega števila)UniPor celične strukture.

Title:
Numerical simulation of thermal and flow conditions in a UniPor cellular structure
Abstract:
The purpose of the thesis is to determine the suitability of UniPore cell structures for the heat exchanger with an analysis of its thermal behavior in different modes of operation, with the help of computer simulations. Master's thesis includes the study of literature in the field of behavior of the cellular structure or porous materials with thermal loads, preparation of numerical models of cellular structures UniPore and implementation of parametric computer simulations of heat transfer through UniPore cell structure made of copper for the same input temperatures for different heating medium (water, air) and liquid flow velocities along the pores. Flow regime will be limited to the laminar flow of a viscous fluid. Based on simulation of detailed geometry is necessary to create a simplified model of the heat exchanger taking into account the concept of porous media. The results of computer simulations will be used to describe the hydrodynamic characteristics (pressure drop) and thermal properties (thermal diffusivity value of the porous medium and the overall Nusselt number) of UniPore cell structures.
