I carried out an experiment in a wind tunnel and it shows that as I increase the air velocity the water temperature drop is bigger but the rise in air temperature going through the radiator becomes lesser. Am I wrong to understand that its due to the fact that the air mass flow rate has increased therefore the air stays in "one" place for less time so it doesn't have the time to reach the higher temperature ? So the faster your car goes the less difference there is in between the air temperature going in and coming through the radiator ? I keep contradicting myself thinking the air temperature rise should increase with air velocity as it is dissipating more heat. Can anyone explain this to me please ? Thank you. For ease of comparison I have attached a graph too.
