mjfawke Posted January 15, 2008 Share Posted January 15, 2008 Link here. It's a paper looking at aerodynamics of the SSI Airline Saloon (1934-1935) and 260Z. Quote Link to comment Share on other sites More sharing options...

Nismo280zEd Posted January 15, 2008 Share Posted January 15, 2008 Was reading the paper and I'm kind of confused with this statement. "It was shown in Section C that both cars had large cooling system drag coefficients despite the ducting present, which could be improved by rounding the inlet and reducing the diffuser angle to less than 15(deg)" What is he calling the diffuser on the front of the car? The hood angle? Quote Link to comment Share on other sites More sharing options...
mjfawke Posted January 15, 2008 Author Share Posted January 15, 2008 I'm thinking hood (bonnet) and the lower panel. Anything higher than 10-15 degrees causes flow separation and turbulence, and according to Carrol Smith, not having a radiused entry the the air inlet duct significantly increases the chances of flow separation. Other food for thought - The Electromotive 280ZX turbo had pretty large changes in angles on the radiator inlet duct, but had internal flow guides. Subaru WRX intercooler in stock form doesn't have flow over the front of the IC core without additional flow guides. Quote Link to comment Share on other sites More sharing options...
