Vortex generators are disclosed herein. An example apparatus includes a housing including a surface. The example apparatus also includes a bimorph actuator (300) disposed in the housing. The bimorph actuator includes a first bimorph (302) beam having a first portion fixed relative to the surface. A blade (200) is rotatably coupled to the bimorph actuator (300), and the bimorph actuator (300) is to rotate the blade (200) to extend a portion of the blade (08) through the surface to generate a vortex in a fluid flowing past the surface. |
