Abstract: | In the present paper, we consider the heat transfer of non-Newtonian liquid flows moving in convergent- divergent channels
with common boundary. The case of flows moving in opposite directions was addressed. At the common boundary, continuity conditions
for temperature and heat flow were adopted. A mathematical model, a calculation algorithm, and simulation data are reported.
Plots of numerical data characterizing the channel flows are presented. A comparative analysis of heat transfer in smooth
and convergent-divergent channels is given. |
