Difference Between Stationary Study and Time Dependent Study.

Hello,
I am new to Comsol, but I have a general question between study step types. Is there a difference between Stationary Study and Time Dependent Study when it comes to computation fluid dynamics modelling? I am trying to simulate the mixture between two gases in a pipe (a gas flows from an injection pipe into a main pipe where the two gases will mix), and I simulated they system using the Stationary Study. I also replicated the exact same simulation using the Time Dependent Study, but I get different results such as the concentration or mole fraction of the gases in the pipe.
Thank you for your time and help.

Have you given your time-dependent study sufficient time such that you see no change in ALL parameters?

For my time-dependent study, I set up the simulation to take about 600 sec (or 10 minutes) so maybe that could be an issue. Thank you for your suggestion, I will try to increase the simulation time and compare the results.
