I am trying to find some benchmark results (transient) to validate my code, preferably DNS result with low Re number. Here I use "transient" to represent the time-dependent data: for example, the lid-driven case, I need the intermediate data of each time step from static to fully developed. Anyone has suggestions?
thanks a lot.

I think your question is not well-posed... if you refer to DNS of turbulent flows there is no sense in considering deterministic comparison of data at each time... you can compare only the statistics.

For example you can compare statistics for channel flow with an oscillating (in time) pressure gradient...

Otherwise you can use some time-dependent analytical solution of the NS equations at very low Re
