A mixed conditional

Yes.

When we use 'would' for a future event,there is always a possibility, however remote, that the event will happen. In your sentence, "If I had studied" tells us that the speaker did not study, and that the future travel will not happen.

We'd therefore say "If I had studied hard yesterday, I would have travelled tomorrow.".

But the opportunity of having a travel is not lost totally! They still, however improbable, could travel tomorrow despite the failure of studying yesterday. I think the mixed form makes more sense because the result clause has to do with the future. (tomorrow)

SadeeIf I had studied well yesterday, I would travel tomorrow.

I think I'd change it a little to make it sound a little more realistic.

If I had finished my work yesterday, I would be traveling tomorrow.

The 'If I had studied yesterday' precludes that possibility.

CalifJimIf I had finished my work yesterday, I would be traveling tomorrow.

That one works.
