Two geometries of porous deposits are known to form on heat transfer surfaces. When boiling is not present, a homogeneous layer typically forms. When boiling is present, a heterogeneous porous layer with densely populated chimneys is generated. Typical dimensional characteristics of the deposits are 25 {mu}m thick, 2.5-{mu}m chimney diameter, 3 x 10{sup 9} chimney/m{sup 2}, 0.6 porosity, and 0.5-{mu}m particle diameter. Observations indicate that porous layers with chimneys give much better heat transfer performance than the layers without chimneys. This study considers both types of layers and constructs models for the thermal performance of each under boiling conditions.
