Default Natural convection with High Ra

I am simulating the natural convection in an enclosed cavity (H/W=4)with high Ra up to 10^12 and the time averaged Nu at hot wall for Ra<=10^10 are agree well with those by Le Quere et al in 1995. But I have not found the results for larger Ra now. Would you please tell me where I can find them.

Thanks in advance.

See Betts, P. L., and Bokhari, I. H., 2000, "Experiments on turbulent natural convection in an enclosed tall cavity", Int. J. Heat & Fluid Flow, 21, pp. 675-68. It seems to me that Ra based on the heghit is about 2e+10 there.

Alexey.
