Abstract
An experimental study was carried out to investigate the effects of biomimetic vortex generators (biomimetic-VGs) on the aerodynamic performance of the NACA0015 airfoil. Aerodynamic force measurements and titanium dioxide (TiO2) based flow visualization technique experiments were performed for test models at Re=1.2×105. Aerodynamic force measurement experiments were carried out in the wind tunnel at angles of attack of 0°-18° with an increment of 1°. As a result of the experiments, it was revealed that the lift coefficient (CL) increased and the drag coefficient (CD) decreased by using the seaconchshell structure as a vortex generator for the wing model. In addition, it has been observed that biomimetic models were shifted stall angle of the airfoil by 1°. In the surface oil flow visualization experiment results, the flow structure around the NACA0015 airfoil of biomimetic models (BMs) was revealed and interpreted. Moreover, it has been revealed that the aerodynamic performance of the airfoil increases as a result of the use of BMs. It is also revealed that the seaconchshell structure, which has not been studied before in the literature and which is the subject of this study, can be used as an effective flow control device.
期刊介绍：
Bioinspiration & Biomimetics publishes research involving the study and distillation of principles and functions found in biological systems that have been developed through evolution, and application of this knowledge to produce novel and exciting basic technologies and new approaches to solving scientific problems. It provides a forum for interdisciplinary research which acts as a pipeline, facilitating the two-way flow of ideas and understanding between the extensive bodies of knowledge of the different disciplines. It has two principal aims: to draw on biology to enrich engineering and to draw from engineering to enrich biology.
The journal aims to include input from across all intersecting areas of both fields. In biology, this would include work in all fields from physiology to ecology, with either zoological or botanical focus. In engineering, this would include both design and practical application of biomimetic or bioinspired devices and systems. Typical areas of interest include:
Systems, designs and structure
Communication and navigation
Cooperative behaviour
Self-organizing biological systems
Self-healing and self-assembly
Aerial locomotion and aerospace applications of biomimetics
Biomorphic surface and subsurface systems
Marine dynamics: swimming and underwater dynamics
Applications of novel materials
Biomechanics; including movement, locomotion, fluidics
Cellular behaviour
Sensors and senses
Biomimetic or bioinformed approaches to geological exploration.
