... distribution and pressure drop in a disk cavity with c eff < 0 was established. The model employs the turbulent boundary layer integral method, and von Karman's assumption of velocity profile and wall shear stress for a free disk. The calculation results of the swirl ratio in the cavity are in good...

... the highest strain tolerance ( ST ), because thin wall designs have a lower E-modulus [ 32 ]. Triangle cells do have the minimum pressure drop, because of its reduced Fanning friction factor, as indicated in Table 1 , given the same hydraulic diameter. Table 3 Comparison of different channel...

... except for the two additional baffles. The results indicate that the flow distributions of Models C and D are much more uniform under different inlet Reynolds number, especially in the high inlet Reynolds number. Although the flow distribution of Model D is the best, its pressure drop is 2.6 times higher...
