With respect to "Surface details this small cannot be analysed with anything below a 1/2-scale model" were exactly this was discussed? That is a clay model not a car!

*whether they have a PhD or are from India is not germane to the topic.
*I have a B.S.,Mechanical Engineering Technology.
*Where these criteria were discussed is nowhere in their presentation,as they obviously didn't know what they didn't know with respect to aerodynamics,or dynamic similarity,and it reflects the fact that they don't understand critical Reynolds number and verisimilitude (absolutely critical to testing success),which is discussed elsewhere in the literature I've studied over the last 40-years.
*Of course it's a model.
*The PhD's who run 'real' wind tunnels have published reports stipulating that certain body features cannot be adequately tested at scales below 1/2-scale,sometimes it requires full-scale testing,or full-scale CFD.
