| Popis: | 96 Fluid flow and heat transfer phenomena in nowadays has been exist in nature and others field, while the numerical analysis of CFD (Computational Fluid Dynamics) can simulate these complex physical phenomena systematically. In recent years CFD has widely been used to analyze the airflow structure of vehicular cabin, which to step out the development of research time and resources saving, and accurate analysis of various thermo-flow field inside a vehicular cabin. This study will carry out the simulation and analysis of thermo-flow field for Ford E350 cabin that establish the influence of the thermal comfort of manikins which the internal configuration were already modified. Research methods used CFD software - FLUENT module for the thermo-flow of temperature, pressure and velocity distribution, and take into account the solar radiation, physiological heat of manikins and heat sources, in addition, the grid adaption technology will use to increase the accuracy of simulation results and quote from PMV and PPD index of ISO 7730 to estimate the thermal comfort of manikins. Simulation results show that by the change of internal configuration of vehicular cabin, the thermal comfort is not generally comfortable, because the vent location of inlet and outlet can not removed the heat effectively from the inside, in the future, we can apply an air flow management technique to improve the thermal comfort for its. |
