The errors reported here are on the basis of the entire fluid layer. The three different errors reported are:

In these definitions, and are the hot and cold temperatures. and are the temperature cariables of the original and the reconstructed field respectively. Results for the error level distribution in the fluid layer have also been determined. The distribution of the absolute error as a percentage of the error has been presented in the three zones as before namely
