Thermal insulation of buildings is one of the most effective energy conservation methods. However, most of the building walls still have little or no insulation despite Turkish Thermal Insulation Standard in Turkey. Four provinces from different climate zones, obtained by the Turkish Thermal Insulation Standard; Izmir (1st zone), Istanbul (2nd zone), Ankara (3rd zone), and Erzurum (4th zone) were selected for analysis. The aim of this study is to investigate of efficient parameters on optimum insulation thickness (OIT) in terms of the order of importance using theoretical‐Taguchi coupled method. The OIT was considered as performance parameter. An L16 (43*22) orthogonal array was chosen as a design plan for the five parameters (wall, insulation, fuel type, heating degree‐day (HDD) and lifetime). The results were analyzed using signal‐to‐noise (S/N) ratio and analysis of variance method. Furthermore, contribution ratios for each parameter on OIT. HDD value is the most effective parameter on the OIT with a contribution ratio of 34.53% percentage of the total effect. The second most effective parameter is insulation type with a contribution ratio of 30.6%, and the effect of fuel type on the OIT is contribution ratio of 24.18% and it is followed by lifetime (8.2%), wall type (0.67%), respectively. Consequently, daily mean temperature of cities is most important parameter on OIT. Insulation and fuel type effect is less than HDD, the impact of fuel type is close the impact of insulation type, and the effect of wall type is less than the other parameters. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1824–1831, 2017

“…Taguchi method and ANOVA are generally used in experimental studies. Recently, however, there are numerous computational fluid dynamics studies [31][32][33][34][35][36] coupled with the Taguchi method and ANOVA. In this way, the number of numerical analysis decreases in the study and time is saved.…”

“…Besides that, the other type of insect of interest is the fruit fly. Zhang et al [ 41 ] were inspired by hovering fruit flies in developing a flapping MAV wing model in hovering flight using CFD and ANSYS Fluent. The authors validated the study with previous experimental work and obtained good agreement in time-averaged lift coefficients.…”

In many modern engineering fields, computational fluid dynamics (CFD) has been adopted as a methodology to solve complex problems. CFD is becoming a key component in developing updated designs and optimization through computational simulations, resulting in lower operating costs and enhanced efficiency. Even though the biomimetics application is complex in adapting nature to inspire new capabilities for exciting future technologies, the recent CFD in biomimetics is more accessible and practicable due to the availability of high-performance hardware and software with advances in computer sciences. Many simulations and experimental results have been used to study the analyses in biomimetics applications, particularly those related to aerospace engineering. There are numerous examples of biomimetic successes that involve making simple copies, such as the use of fins for swimming or the mastery of flying, which became possible only after the principles of aerodynamics were better understood. Therefore, this review discusses the essential methodology of CFD as a reliable tool for researchers in understanding the technology inspired by nature and an outlook for potential development through simulations. CFD plays a major role as decision support prior to undertaking a real commitment to execute any design inspired by nature and providing the direction to develop new capabilities of technologies.

“…In this paper, two control variables are used: flapping frequency f and sweeping bias φ 0 . The flapping frequency mainly affects the magnitude of the aerodynamic force [37] while the sweeping bias is used to control the pitch axis. The two control variables have been commonly used in the control of FWMAVs [38][39][40].…”

Flapping-wing micro air vehicles (FWMAVs) have the capability of performing various flight modes like birds and insects. Therefore, it is necessary to understand the various flight modes of FWMAVs in order to fully utilize the capability of the vehicle. The unique flight modes of FWMAVs can be studied through the trajectory optimization. This paper proposes a trajectory optimization framework of an FWMAV. A high-fidelity simulation model is included in the framework to sufficiently consider the complicated dynamics of the FWMAV. The unsteady aerodynamics are modeled with the unsteady panel method (UPM) and the unsteady vortex-lattice method (UVLM). The effect of wing inertia is also considered in the simulation model. In this study, transition flight trajectories are searched with the proposed framework. An optimal control problem is formulated for the transition flight from hovering to forward flight and transcribed to the parameter optimization problem with the direct shooting method. The cost function is defined as energy consumption. The same converged solution can be obtained with different initial guesses. The optimization results show that the FWMAV utilizes the pitch-up maneuver to increase altitude, although the forward speed is reduced. This pitch-up maneuver is performed more actively when the target velocity of transition is low, or the wind condition is favorable to acceleration.
