WebCountercurrent exchange in an U-type countercurrent exchanger may have two functions: ( 1) trapping of solutes within the system by transfer of solutes from the ascending to the descending limb and ( 2) preventing water from entering the system by short circuiting from the descending to the ascending limb. WebFeb 26, 2024 · where the transfer vector has the correct signal to be applied in the equation. I'm solving the system with ode15s. I get a reasonable solution when simulating it in co-current (volume flow Vl>0), but when trying in counter-current (Vl<0 and adjusting initial values) the following errors always occurs:
