Abstract: A nozzle and an icing test simulation apparatus with the same are provided to increase reliability of a test result by making droplets having approximately same size and density as the actual droplets in the air. An icing test simulation system includes a liquid supply unit(110), a liquid pressure controller(120), a gas supply(130), a gas pressure controller(140), a spray(150), a cooling unit(160), and a controller(170). The liquid supply unit contains a liquid tank(112) and a gas tank(132). The liquid tank is connected to the spray through a first pipe(114). The liquid tank and the gas tank are connected to each other through a second pipe(116). The liquid pressure controller is installed on the second pipe and controls the amount of gas transmitted from the gas tank. The gas supply unit includes a third pipe(134). The third pipe connects the gas tank and the spray for transmitting the gas from the gas tank to the spray. The gas pressure controller controls pressure of the gas transmitted from the gas tank for changing the size of a droplet discharged from the spray. The spray is installed on a junction of the first and third pipes and mixes the gas and liquid supplied from the liquid tank to spray the mixture to the outside. The cooling unit provides conditions for icing the droplets discharged from the spray. The controller controls operations of the liquid controller and the gas controller.
