Two of the popular ways are blowing (like you suggest) and sucking...either speed up the slow stuff or get rid of it.

The biggest problem will be reducing drag enough that the pump driving the system doesn't use more fuel then is saved. Sucking will also get dust and debris stuck in the pores. If the sheet you are drilling into is structural, you may significatly decrease its strength

Another weird, albeit impractical one I have seen uses flush rollers at the end of an abrupt cutoff to encourage flow into an area of separation.

One cheap technology that could be crossed over to cars is gap seal tape.
