Low Re correction for K-W(1998)
 
For 1998's K-W turbulence model. Low Renoald correction is necessary for some folws. but how to calculate the i meet problems in deal with terms such as A_ij*A_jk*B_kl how to express it ? thanks

Probably it is Einstein notation for tensors which supposes summation of multiple indexes. If it is so then A_ij*A_jk*B_kl is the second rang tensor R_il:

A_ij*A_jk*B_kl = R_il =

SUMM(SUMM(A_ij*A_jk*B_kl)) for_all_l and for_all_j
