If the inlet velocity is 1.7 m/s, then the Reynolds number is even lower. Further, it's very clear from Fig. 13 (and also Fig. 11) that the inlet velocity is not anywhere close to 1.7 m/s. I suggest you contact the author and ask for clarification.

Regarding the flame shape, I think the difference is due to the thermal condition at the walls. You are applying a zero-flux condition. Fig. 7 in the paper shows that the walls are cooled. However the exact thermal boundary condition applied in the paper is unknown.

The message "dasac failure at temperature .." is usually caused by the presence of some excessively large numbers in the chemical mechanism kinetic data. They can be disregarded if the iterations are converging. I don't think this is the cause for getting a different flame shape.
