you could use a spring behind your object, and calculate inline reaction force from deflection.
it will be essential the wind speed is accurately measured
force will represent wind velocity squared *drag coefficient , once calculated the drag coefficient can be used elsewhere, in acceleration calculations for instance.
measuring forces versus wind speed should produce a exponential graph in the form f = v^2 as drag force is proportional to square of velocity
if you translate the action into freefall , at terminal velocity the forces balance,
down = mass * gravity acceleration ( newtons)
up = velocity ^2 * drag coefficient (newtons)

What is a cascade wind tunnel?
it is a simulation of real running turbine or compressor blades, since it is difficult to study a rotating and mooving machin, its better to fix the blade and let the air circulate, then study all the parameters... bilal el samad mechanical engineer

How wind tunnels work?
a wind tunnel works by turning on a gigantic fan in a round tunnel they place the car SUV etc. in the tunnel and turn the fan on to see if its aerodynamic since we cant see air they put a fog machine to make stream of fog to see the aerodynamics of the car the faster the fog passes the more aerodynamic it is

Computer models are used extensively and in a wind tunnel
Who uses a wind tunnel and why?
Engineers use them to study the aerodynamic properties of items they are designing, like cars, aircraft, etc.

How do you measure aerodynamics?
Aerodynamics is a branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids. However if you were interested in the flow of fluid around a moving object, you simply stick it into a wind tunnel.
What should you use for smoke in your homemade wind tunnel?
The easiest thing to use is Dry Ice. Make sure it funnels to the top and you can add water at a controlled rate.
