Abstract
An enhanced boiling apparatus includes a substrate having at least one heated region, at least one outer surface, and one or more asymmetric shaped cavities extending into the substrate along the at least one outer surface. Each of the one or more asymmetric shaped cavities has a sidewall which intersects at a corner with a bubble pathway surface with a different slope from the sidewall. Each of the asymmetric shaped cavities is configured to non-gravitationally direct fluid that is moving along the sidewall out along the bubble pathway surface.
