Can you define what a "flow" is?

flow is all packets belonging to this quintuplet (src ip, dest ip, src port, dest port, protocol)

Probably the Conversations in the Statistics menu should give you a pretty good insight.

Can also get with tshark:

$ tshark -r ./ultpcap2.pcapng -q -z conv,tcp > tcp.conv
$ tshark -r ./ultpcap2.pcapng -q -z conv,udp > udp.conv
