From: Theoretical investigation of transgastric and intraductal approaches for ultrasound-based thermal therapy of the pancreas

Surface h (W/m2/°C) T f (°C)
Transgastric catheter 1000 [16, 75] 22
Intraductal balloon 500 [13, 63] 22
Aorta 511 37
Vena cava 184 37
Large vessels 750 37
Small vessels 1000 37
  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
