Abstract
U ovom radu izvršena je numerička analiza nestacionarnih toplinskih naprezanja koja se javljaju u kućištu, statoru mikroturbine tijekom puštanja u rad. Izmjena topline između radnog fluida, toluena i statora opisana je primjenom poznatih eksperimentalnih korelacija za koeficijent prijelaza topline. Mikroturbina koja se obrađuje dio je Rankinovog organskog ciklusa za koji se kao radna tvar koristi toluen. U okviru ovoga rada dan je kratki opis rada mikroturbina i Rankinovog organskog ciklusa. Nakon uvoda opisan je matematički model te je prikazan postupak diskretizacije matematičkog modela primjenom metode kontrolnih volumena. Dalje se u radu opisuje izrada mreže, postavljanje numeričkog modela koji će se rješavati, daju se svojstva materijala iz kojeg je izrađen stator mikroturbine, početni i rubni uvjeti za rješavanje diskretiziranog matematičkog modela te postupak primjene poznatih eksperimentalnih korelacija za koeficijent prijelaza topline. Nakon numeričke simulacije za koju je korišten programski paket OpenFOAM, daj se analiza rezultata.
Abstract (english)
This paper presents a numerical analysis of unsteady thermal stresses that occur in the housing of microturbine during commissioning. The heat exchange between working fluid, toluene and stator is described using known experimental correlations for heat transfer coefficient. Microturbine presented in this paper is part of the organic Rankin cycle which uses toluene as working fluid. There is also short general description of microturbines and organic Rankin cycle. Mathematical model is presented after introduction. Discretization of mathematical model using finite volume method is briefly described. Next, the paper describes the creation of the mesh and the way the numerical model is set. Then the properties of material which makes the stator of microturbine is given, initial and boundary conditions for solving discretization of mathematical model and application of known experimental correlations for heat transfer coefficient. After numerical simulations is complete using the software package OpenFOAM, the analysis of the results is given.
