Static mixer
A static mixer created using an additive process is disclosed. The static mixer is enabled to homogenously blend two fluids flowing in a pipe. The static mixer exhibits zero contact angle in relation to the two fluids being mixed within the pipe. The static mixer exhibits a first contact angle with the first fluid and a second contact angle with the second fluid. The first contact angle is either between 0 and 30 or greater than 85. The second contact angle is either between 0 and 30, or greater than 85.
1. A method of making an emulsion, the method comprising:
providing a static mixer having a smooth surface and made from a material;
providing a first fluid that has a first contact angle with the surface,
providing a second fluid that is immiscible with the first fluid and has a second contact angle with the surface,
wherein the first fluid and the second fluid are combined at a water-to-oil ratio greater than 70; and
mixing the first fluid with the second fluid using the static mixer wherein the first contact angle and the second contact angle are both between 0 degrees and 30 degrees.
2. The method of claim 1 , wherein the static mixer and a pipe housing the static mixer are a unitary construction.
3. The method of claim 1 , wherein the method further comprises making the static mixer using an additive manufacturing process.
4. The method of claim 1 , wherein the static mixer exhibits one or more surface characteristics, wherein the surface characteristics comprise one or more surface structures, porosity, and combinations thereof.
5. The method of claim 1 , wherein the method further comprises manufacturing the static mixer by a step selected from the group consisting of selective sintering, stereolithography, fused deposition modeling and selective laser melting, and combinations thereof.
