I am running ANSYS fluent simulation flow over naca 0012 airfoil. So far the lift coefficient is similar with the published papers. The problem is drag coefficient is different so much in term of value compared to published papers. I have check my mesh quality and boundary condition, it shows...

The reynolds number for internal flow are much more easier. My airfoil is NACA 0012 symmetrical airofoil. Currently running on CFD simulation

In which range of Reynolds numeber is laminar flow for airfoil? Is it Re < 5 x 10^5? How about turbulence case?

The acrylic made aerofoil seems can't give me the shape that i want. There are some deformation at the leading edge, so i decided to try other method. Is there any other techniques to fabricate an aerofoil ?

My title of project is flow visualization of NACA 0012 aerofoil analyzed by PIV. Therefore i have to focus on naca 0012.

Thank you everyone who had help me. Currently my college PIV is having some trouble so what i can do is try it in simulation.

Hey guys i would like to ask how to determine whether my velocity streamline is correct? The velocity streamline shown in picture is the result of ANSYS fluent simulation.

Correct me if i have mistake. Initially i never think of index of refraction of acrylic, that's why i believe laser beam can pass through acrylic smoothly. ( As shown in picture 1 ) I want to capture flow pattern as shown in picture 2. Since the laser bream will be refracted, then i...

I agree with you in term of refraction. So any suggestion for transparent aerofoil? :(

Based on picture 1, this is my expected experiment configuration. I use acrylic for so that the PIV laser beam can pass through the transparent acrylic. The picture 2 shows that the shape (with flow pattern) i would like to capture from CCD camera (from top view). Any comment for my...

My experiment is to measure external fluid flow patterns which obtained from Particle Image Velocimetry, in other words is flow visualization of aerofoil NACA 0012 inside wind tunnel. My experiment is not going to analyze the attack of angle, that's why my aerofoil are required to mount in...

I am doing a wind tunnel experiment on aerofoil. So i need some idea to mount my aerofoil in the test section. The aerofoil is made of acrylic. So which type of stick will suitable for my aerofoil mounting. The configuration as shown in picture that attached. (Picture taken from google image).
