Force estimation of mechanical removing processes of mushy structure in an aqueous solution

In a system of producing liquid ice with mechanical removing processes of mushy structure in an aqueous solution, a solid layer as thermal resistance does not stack up on a cooling surface. It prevents refrigeratorʹs COP dropping and also prevents ice production rate dropping. However, some extra energy is needed for mechanical removing processes of the mushy structure from cooling surfaces. In this paper, the required force for removing the mushy structure is expressed as a function of experimental conditions based on bending-beam theory. The mushy structure is regarded as an elastic body. The estimated values of modulus of elasticity and values of adhesion force are reasonable compared with the observed results. Parameters that affect on mode difference, maximum force and steady force are shown.
