    Numerical Simulation of Different Ventilation Systems in an Airplane Cabin
    (2022) Özerdem, Barış; Bilir, Levent; Celik, Hasan
    Airplanes are the most popular way of transportation worldwide, especially for long haul. It facilitates the growth of global trade as well, besides promoting tourism and other employment developments. Passenger comfort and hygiene inside an airplane cabin became main concern for aircraft manufacturers. The possibility for a potential spread of infectious virus or bacteria even maximized this concern. Therefore, supplying sterile and particle-free air inside the aircraft cabin became extremely crucial more than ever. In order to ensure comfort and hygiene, regardless of the environment conditions inside the aircraft cabin, paved the way for researchers to focus on this topic, recently. It is obvious that, an important precaution for the spread of micro-organisms can be selecting an adequate air ventilation system inside the airplane cabin. In this study, a part of an airplane passenger cabin is modelled for four different scenarios. The streamlines of air, which is sent to the cabin from air ducts, are obtained and air flow path is observed for the investigated cases. The results of the numerical simulations are presented as the outcomes of this study. It is observed that the air mixing between different seat rows occur slightly only for sidewall supply and bottom return mixing ventilation and displacement ventilation systems, whereas the air mixing for the same seat row is seen for all ventilation systems. In conclusion, sidewall supply and bottom return mixing ventilation system is found the most appropriate one, even though it causes air recirculation at the same row seats.

    Future Aircraft Concept in Terms of Energy Efficiency and Environmental Factors
    (Pergamon-Elsevier Science Ltd, 2017) Baharozu, Eren; Soykan, Gurkan; Özerdem, Mehmet Barış
    Currently, the importance of aircraft efficiency has increased with the rise in jet fuel prices. Due to high fuel prices and compelling pressures to address environmental concerns, different aircraft concepts have been taken into consideration in recent years. These concepts not only include the usage of varied fuel types but also the usage of more electricity. According to the literature on the topic, the most conspicuous alternative fuel type is hydrogen. In this paper, traditional aircraft, more electric aircraft, and liquid hydrogen-fueled aircraft are compared by using a multi criteria scoring method. As a result of this comparison, a future aircraft concept for long distance flights is proposed combining the more electric concept and the liquid hydrogen fueled concept. The suggested future aircraft concept is better than the traditional aircraft with regard to efficiency, cost, and environmental impact. In conclusion, the proposed aircraft concept for long range is an unavoidable choice for the future of the aviation sector to increase energy efficiency and decrease harmful environmental effects.

    Academic Performance Management Policy for Changing Roles of Universities in Innovation Systems
    (Institute of Electrical and Electronics Engineers Inc., 2017) Ozcan S.; Ozyazici M.S.; Ozerdem M.B.
    The purpose of this study is to establish a new performance measurement method for academic actors for their changing roles in innovation systems. The widely accepted triple helix and systems of innovation models show changing and overlapping roles of academic, industrial and governmental actors. In previous innovation systems, universities were not focused on applied research and technology transfer as much as they are now. Current literature shows a changing role of universities and importance of their involvement in innovation systems. Although academic organizations' roles have changed in innovation systems, academic performance measurement systems (APMS) are not adapted to examine innovation related performance factors. Many APMS focus on key performance indicators (KPIs) such as; publications, research projects and patents. However, the new APMS needs to assess the activities and processes that are related to innovation, such as; technology transfer processes, collaborative innovation activities, consultancies and academic spin-offs. For this study a new APMS is applied according to the needs of universities by using a synthetic data based on an engineering department's KPIs. APMS scores are calculated based on the cumulative metric of all research and innovation activities and, weighted according to the needs and considerations of the university. The results of this study show that many of those academicians who have great performance in publications and academic research do not necessarily have high-level performance in innovative activities. In fact the results show that those who had high points in some measurements have very low performance in others. For the management point of view, it may be more effective to position academicians for different roles and assess their performance accordingly as innovation-targeted, teaching-targeted and research-targeted academicians. © 2016 Portland International Conference on Management of Engineering and Technology, Inc.
