yes, you can save the output of ovs-ofctl dump-flows to a file, and
use ovs-ofctl add-flows to
add them back. "man ovs-ofctl' for more detail.

Openflow are usually installed by a controller, ovsdb usually
stores configuration information that tends to be more static compare
to openflow flows.
 
If you don't want to use a controller, and only has a fixed set of flows, you
can load them from a file, as discussed above.
