“…A number of computational methods have been developed for predicting turbulent velocity and temperature fields in triangular array of rods. These include the graphical methods of Dwyer (1966, N3), the approximate analytical method of Nijsing et al (1969 and1973, N3), Johannsen (a) et al (1971,03), Axford (1967, N3), and Magee and Tromel (1966, N3), the numerical methods of Dwyer and Berry (1972, N3), Dwyer, Berry, and Hlavac (1972, N3), Bender and Magee (1969, N3), and Meyder (1974, N3), and the finite element methods of Slagter (1975Slagter ( , 1978.…”
