Metoda stochastycznych różnic skończonych w problemach przepływu ciepła i ruchu wilgoci w elemencie betonowym
Języki publikacji
Abstrakty
A stochastic finite difference approach based on stochastic finite elements is proposed for heat and mass transfer modeling. Porous structure with random material properties is investigated. The theoretical formulation of the problem is described. A system of partial differential equations is obtained and solved for first two probabilistic moments of the random temperature field. Example of stochastic thermal analysis in concrete structure with random material parameters are given.
W artykule zastosowano metodę stochastycznych różnic skończonych do analizy problemów przepływu ciepła i ruchu wilgoci. Przedstawiono sformułowanie teoretyczne problemu. Badano porowatą strukturę z losowymi parametrami materiałowymi. Do rozwiązania zagadnienia zastosowano metodę perturbacyjną.
