A numerical solution of the coupled heat transfer process during freezing on a finned tube

Abstract EN

In the present study, a numerical model is proposed to analyze the freezing processes on finned tubes under coduction-controlled freezing, i.e., the liquid is set at its fusion temperature during the freezing process.

Difficulties associated with the complex structure of the time wise changing physical domain (frozen region) has been overcome by applying a grid generation technique in conjunction with an ADI finite difference formulation to solve the governing equation through the frozen layer.

The numerical results thus obtained are satisfactorily compared with the available experimental results of Sparrow et.

al.

[5], and the numerical procedure was found efficient and accurate.
