The phrase "assumed surface" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or any field where a surface is taken for granted or considered as a basis for analysis or calculations.
Example: "In our calculations, we will use the assumed surface of the material to determine its thermal properties."
Alternatives: "hypothetical surface" or "presumed surface".
The governing differential equations are then integrated with these assumed surface boundary conditions.
This assumed surface Y contains linear, squared and cross-product terms of variables X i 's.
If typical values for rock density (ρr= 2.67 [g/cm3]) and an assumed surface height change (Δh = −10 [mm]) are substituted into this equation, the change in gravity is found to be Δg = 1.97 [µgal].
The comparison of the measured KJQ values and conservatively estimated stress intensity factors at an assumed surface crack shows that the cladding would remain intact during pressurized thermal shock transient.
Dashed lines are gradients in wells (locations in Figs. 2, 3) published by Thienprasert and Raksaskulwong (1984), which we extrapolate upward to an assumed surface temperature of 26 °C.
(a d) Spring-time mean column ozone decrease (DU) in SLIMCAT in 2020, 2040, 2060 and 2080 calculated as run no_CH2Cl2 minus run Scenario 1 (assuming surface CH2Cl2 continues to increase at the mean rate observed over the 2004 2014 period).
(a) Difference in zonal mean annual mean ozone between run Scenario 1, assuming surface CH2Cl2 continues to increase at the mean rate observed over the 2004 2014 period, and run no_CH2Cl2 in 2050.
Classical models, developed for corrosion-resistant alloys, assume surface layers (commonly known as passive layers) are inherent to the metals/alloys.
The heterogeneous gasification reaction was modeled based on the available experimental data using the shrinking core model (assuming surface reaction is the limiting step).
By using two measurement methods we have obtained the two independent elastic constants of glass (assuming surface isotropy and homogeneity).
Intraparticle resistance to mass transfer is low, which can be explained by assuming surface diffusion of the adsorbed molecules on the porous carbon.
