Figure 5From: DNA molecule stretching through thermo-electrophoresis and thermal convection in a heated converging-diverging microchannelRelative velocity of the buffer solution convection. Velocity gradient at different electric fields and at a definite channel inlet x = 14.5 mm (a, b, c) and different channel velocity profile (d, e, f) at y = 0 at different channel positions (a, b, c) with different heating temperatures and electric strengths.Back to article page
