Abstract: This research is a study to find a suitable air supply pattern inside a fire nozzle, a liquid fuel-type porous material by a 2D particle Image Velocimetry (PIV) method. Different air supply patterns directly affect the degree of mixing intensity occurring inside the combustion chamber, which is an important factor in determining combustion performance inside the burner. Therefore, this study conducted an experiment to study the influence of the air supply pattern that causes circulating flow that affects the degree of turbulence intensity (TI). The circulating flow occurs by supplying air into the cylindershaped combustion chamber in three directions around the wall of the combustion chamber. Study the mixing characteristics that occur inside the combustion chamber of the burner using the 2D PIV method. The experiment was conducted at room temperature without burning (Cold test). The burner used in the experiment was made of cylindrical rolled metal and used clear acrylic pipes as combustion chambers to be able to observe the flow behaviors inside the combustion chamber. Replace the flow of fuel vapor with air mixed with smoke with the same Reynolds number (Re). Conduct experiments to study the flow and mixing behaviors occurring at each of the various air supply angles: 0, 15, 45, 75 and 90 degrees (refer to tangent line), respectively. Each air supply angle experiment will supply air with a total of four flow volume values of 10, 20, 30, and 40 m3/h, respectively, in Reynolds number form. The study found that at 75 degrees of air supply, circulation flows occurring inside the combustion chamber have the highest turbulence intensity and increase with increasing air supply rates
