1) diffusion along a concentration gradient under isobaric condi-tions, 2) diffusion along a thermal gradient, which may give rise to a concentration gradient as ice sublimes or molecules desorb from the regolith, and 3) hydraulic flow, or mass motion in response to a pressure gradi-ent. _____ transport regolith through laminar flow. a.

The development of the basic theory is described in texts by Rogers and Mayhew (1967) . In a modification of the approach employed by Lin et al. (2009) , a simpler result is obtained by assuming that the velocity of flow within the surface pores of the wheel is v s ( Zhang et al., 2013 ). This important technique offers the potential for significant reduction in drag and, thereby, for large increases in range or reductions in fuel usage for aircraft. For transport aircraft, the reductions in fuel consumed as a result of laminar-flow control may equal 30 percent of present consumption. Laminar flow is a gentle flow in which the streamlines are not crossing each other, that is, they are parallel to one another.

. 78 The Darcy’s Law Interface 81 Domain, Boundary, Edge, Point, and Pair Nodes for the Darcy’s Flows are those that do not change in geometry or flow characteristics from cross section to cross section are said to be uniform. Remember that flows can be either steady (not changing with time) or unsteady (changing with time).
The laminar flow model (LFM) is based on the boundary layer theory of laminar flow past a flat surface. The development of the basic theory is described in texts by Rogers and Mayhew (1967) . In a modification of the approach employed by Lin et al. (2009) , a simpler result is obtained by assuming that the velocity of flow within the surface pores of the wheel is v s ( Zhang et al., 2013 ).
The geometry consists of a tube with three twisted blades of alternating rotations. The Laminar Flow and Transport of Diluted Species interfaces are used with a Stationary study type. Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass.
In turbulent flow we can use either the Colebrook or the Zigrang-Sylvester Equation, depending on the problem. Both give equivalent results within
The interconnectedness of the void (pores) allows the flow of one, or more, fluids through the material.

laminar flow on transport aircraft. The difficulty of maintaining laminar flow on this type of aircraft is exacerbated by the wing sweep, which has several associated mechanisms that can lead to transition. Understanding each of these mechanisms and how they can be controlled is essential for developing laminar flow technology.
