Abstract
A method and apparatus for simulating icing conditions using a wind tunnel is provided. Water drops are sprayed from a number of nozzles into the wind tunnel. A mist of cryogenic liquid is sprayed into a path of the water drops downwind of the nozzles in the wind tunnel, wherein the mist of cryogenic liquid turns the water drops into ice crystals.

A method of simulating icing conditions using a wind tunnel, the method comprising:
- spraying water drops from a number of nozzles into the wind tunnel;
- and
- spraying a mist of cryogenic liquid into a path of the water drops downwind of the nozzles in the wind tunnel, wherein the mist of cryogenic liquid turns the water drops into ice crystals.
An icing simulation system comprising:
- a wind tunnel;
- a number of nozzles configured to spray water drops into the wind tunnel;
- and
- a heat exchanger chamber downwind from the nozzles, wherein the heat exchanger chamber is configured to spray a mist of cryogenic liquid into a path of the water drops.
