WebApr 13, 2024 · A further increase in P r leads to the critical Grashof numbers in the region of smaller k. As a result, one has a finite jump from k = 1.39 to k = 0.4 (see Figure 15) and the critical Grashof numbers start to decrease. Similar changes in G r c and k c take place also for F = 0.5 and F = 0.7. WebTRUE or FALSEFalse1.
