Zonal Model Based Aircraft Passenger Thermal Comfort Comparative Study

• Computational simulations have become during the last decades an essential tool to be used every day sooner in the design chain within the aerospace industry, leading to better decision making and more efficient concepts. However, in the aircraft design field, the thermal comfort of the passengers is not assessed until late design stages due to the complexity and high computational cost of simulating the flow inside it. The present work has the aim to show the Zonal Model approach as a solid early design simulation alternative to conventional CFD. A complete Fractional Step based Zonal Model solver is proposed, able to provide first estimations to the two-dimensional fluid solution, for a given cabin concept, with a low computational cost associated. This solver has also integrated its own automatized mesh generation algorithm along with a Radial Basis Functionsmorphing tool. With this method, a set of comparative studies have been performed for comparing several cabin design parameters attending to the thermal comfort of passengers and crew, giving a demonstration of the capabilities that this Zonal Model approach has for early aircraft design optimization and decision making.
