The phrase "adjacent to the surface" is correct and usable in written English.
It can be used to describe something that is next to or in close proximity to a surface in various contexts, such as scientific, technical, or descriptive writing.
Example: "The temperature of the material was measured at a point adjacent to the surface to ensure accuracy."
Alternatives: "next to the surface" or "close to the surface".
Most other kinds of fluid flow are turbulent except near solid boundaries, where the flow is often laminar, especially in a thin layer just adjacent to the surface.
The pH adjacent to the surface of a film-covered electrode is generally a difficult quantity to measure.
The polarization of the water layer adjacent to the surface was found to be small and affected only the nearest water.
Water molecules adjacent to the surface were found to only weakly interact with the surface and as a result were readily able to exchange with the bulk water.
As a consequence, we predict the existence of a thin tensile-stress sub-layer adjacent to the surface within the boundary layer of near-surface plastic deformation.
The surface velocity us increases with the downwind distance x as us∝x13, and the flow is confined to a boundary layer adjacent to the surface.
The active site is in its resting configuration with K+ as counterion to all charged groups; water immediately adjacent to the surfaces is enriched in HDW; water in the rest of the cavity is enriched in LDW.
By affecting the dynamics of the phase interface adjacent to the heating surface, wettability and surface geometry influence overall nucleate boiling phenomena, from activated nucleation sites to CHF.
However, the quadrilateral surface is adjacent to the articular surface of the acetabulum which makes it possible that a screw here penetrates into the acetabular articular cavity.
A small degree of undersaturation with respect to enamel or dentine leads to initial surface demineralization, followed by a local increase in pH and increased mineral content in the liquid surface layer adjacent to the tooth surface.
This will lead to an outflow of ions (dissolution) and subsequently to a local pH rise in the tooth substance immediately below and in the liquid surface layer adjacent to the enamel surface [ 65].
