An ice can have a unique shape that cross-sectional area in top side larger than the bottom side. The difference of cross-sectional area influence heat transfer of ice, and it can to brine flow around one. Flow around an ice block is similar to flow around the square cylinder bluff body. In this paper, the comparison square body and rectangular body of ice can with an in-lined arrangement with brine concentration variation is investigated. The commercial CFD was used in 3D steady laminar model. SIMPLE algorithm has been employed for pressure and velocity coupling in this simulation. Setting boundary condition in both geometry is velocity inlet, V∞ = 0.002 m/s and wall ice can condition constant temperature T∞ = 0°C. An isotherm profile at the y position is discussed in detail and visualized in 2-D, so do the local surface Nusselt number and average surface Nusselt number. The highest surface Nusselt number average in square geometry the position of y = 0 is 129.67 at the 0.25 concentration of brine and then the lowest surface Nusselt number average in rectangular geometry the position of y = 1 is 0.82 at the same concentration.
