Pressure calculation for flows with moving surface boundaries from particle tracking velocimetry (PTV) 2021 2 .pdf application/pdf 1357 66 56 This makes the current pressure calculation methods inapplicable to a flow domain with deformable moving surface boundaries. The conservation equations of volume, mass, and momentum, governing an isotropic fluid flow, embedded in a control volume (C.V.) with deformable surface boundaries are formulated as [6]: 𝑑𝑉 ð‘‘ð‘Ą = âˆŦ ðŪS ∙ 𝐧𝑑ðī𝑆(ð‘Ą) , (1) 𝑑(𝜌𝑉) ð‘‘ð‘Ą + âˆŦ 𝜌(ðŪ − ðŪS) ∙ 𝐧𝑑ðī𝑆(ð‘Ą) cache/ispiv-83.pdf txt/ispiv-83.txt
