1. A system for visualizing catheter irrigation, the system comprising:
a catheter comprising irrigation holes configured to deliver a second fluid into a first fluid, the second fluid having a temperature different than a temperature of the first fluid;
an imaging assembly configured to acquire images of turbulence occurring in the first fluid when the second fluid is delivered into the first fluid via the irrigation holes, wherein the acquired images comprise schlieren images; and
one or more processors configured to output for display the images of the turbulence.
