Original abstract
This paper deals with the prediction of the air temperature in the aircraft cabin by means of Computational Fluid Dynamics. The simulations are performed on the CFD model which is based on geometry and cabin interior arrangement of Flying Test Facility (FTF) located in Frauhofer Institute. The experimental test flights under three different cabin temperatures were done in FTF and the various data were gathered during these flights. Air temperature in the cabin was measured on probes located near feet, torso and head of each passenger and also surface temperature and air temperature distributed from inlets were measured. The data were firstly analyzed in order to obtain boundary conditions for cabin surfaces and inlets. Then the results of air temperature from the simulations were compared with measured data. The suitability and accuracy of the CFD approach for temperature prediction is discussed.

Tato práce se zabývá předpovědí teploty vzduchu v kabině letadla pomocí počítačové dynamiky tekutin. Simulace jsou prováděny na modelu CFD, který je založen na geometrii interiéru kabiny Flying Test Facility (FTF), jenž se nachází Frauhoferově institutu (Holzkirchen). Byla provedena série experimentálních letů pro různé teplotní podmínky, během nichž byly shromažďovány teplotní data na čidlech umístěných v prostoru kabiny. Teplota vzduchu v kabině byla měřena na sondách umístěných v blízkosti noh, trupu a hlavy každého cestujícího a také byla měřena povrchová teplota stěn a teplota vzduchu distribuovaného z vyústek. Data byla nejprve analyzována za účelem získání okrajových podmínek. Pak se výsledné teploty ze simulací porovnaly s naměřenými daty. Vhodnost a adekvátnost přístupu CFD pro teplotní předpovědi je diskutována v této práci.
