Contour plot of the analytical solutions of the steady state temperature distribution at the cross-section at z=6 mm. The kidney surface temperature Ts=43.0°C, the arterial inlet flow temperature Ta0=37.0°C, and the blood perfusion rate ωb=0.007 m3/s/m3.
Grahic Jump Location
Steady state temperature distributions in the pig kidney during water bath heating. The kidney surface temperature was Ts=43°C, the arterial inlet flow rate Qin=1.55×10−6m3/s, and the initial kidney temperature and the arterial inlet flow temperature were the same, Ti=Ta0=37°C.
