Abstract:V diplomskem delu smo s pomočjo računalniške dinamike tekočin analizirali stacionarno stanje notranjosti ogrevanega avtodoma v zimskih razmerah. Robne pogoje za računalniški model avtodoma smo pridobili z meritvami na realnem vozilu. Rezultate računalniškega modela smo primerjali z rezultati meritev in tako potrdili realnost modela. Na podlagi rezultatov smo predlagali izboljšan sistem ogrevanja, ki je pokazal boljše rezultate kot prvi. Na podlagi rezultatov smo izdelali tudi primerjavo indeksov udobja PMV in PPD, s čimer smo potrdili domnevo o izboljšanju udobja s spremenjenim sistemom ogrevanja.

Title:Numerical analysis of flow and thermal conditions in a motorhome
Abstract:The thesis using computational fluid dynamics analysis of steady state motor home interior heated in winter. The boundary conditions for a computer model of the motor home were obtained by measurements on a real vehicle. The results of the computer model were compared with results of measurements to confirm the reality of the model. Based on the results, we proposed an improved heating system, which has shown better results than the first. Based on the results we made a comparison of comfort indices PMV and PPD, which confirmed the assumption on improving the comfort with a modified heating system.
