Designing a urea heating coil by repeating a urea melting experiment is a very time-consuming and cost-taking task. In this paper, insight on how to design the heating coil of engine coolant type urea tank is provided from numerical analysis. The numerical analysis conditions used in this study were brought from the EPA test procedure, and numerical analysis results are compared with experiment results to investigate reliability of the numerical analysis. The case studies comparing the melted amount of urea of six different urea heating coils are carried out and a following conclusion is reached. Increasing the occupied volume of the urea heating coil by enlarging pitch distance of the heating coil can improve the performance of melting of frozen urea.
