Good explosions in realtime?

Hey i’ve been searching for a long time and I can’t find any good tutorials or anything about making good realtime explosions. I’m planning a game for a class where you use explosions to blast yourself long distances with other things included and I didn’t want the explosions to be just a sphere or something so any links or tutorials to some good explosions would be great, or even just a blend with a nice explosion I could learn off of would be really awesome.

I’ve always used sprites. They seem to do the job fine if it’s always tracking to the camera and finish fairly quickly.
