Shawn,
I have the 22R2 verification cases with me. The y+ for both phases is more than 20 in them. And you can't really play with that setup by changing the density and specific heat values. That affects the LH heat calculation. Also the saturation temp is set as constant in that setup. Incompatible values can cause that. They are indeed fine tuned to match literature.
Can you try without lowRe model?
