  1. Heat transfer coefficients for blood vessels are calculated based upon vessel sizes, which were measured in CT scans, and flow rates [7682] as described by Haemmerich et al. [48]. “Large vessels” included the portal vein, superior mesenteric vein, etc. “Small vessels” included the superior mesenteric artery, splenic artery, hepatic artery, etc
