Pressure induced by a stagnating turbulent field
The Physics of Fluids, 1976The frequency spectrum of a pressure field resulting from turbulence stagnating on a body is shown to be related to the fluctuating dynamic head through a Fourier-like transform along the mean stagnation streamline.

Cavitation erosion often occurs on the surface of many underwater applications, which can cause severe damage to materials and reduce their performance. Since the cause of erosion is the impact pressure induced by the collapse of an individual cavitation

On stagnation pressure increases in calorically perfect, ideal gases
International Journal of Heat and Fluid Flow, 2016Abstract When stagnation pressure rises in a natural or numerically simulated flow it is frequently a cause for concern, as one usually expects viscosity and turbulence to cause stagnation pressure to decrease. In fact, if stagnation pressure increases, one may suspect measurement or numerical errors. However, this need not be the case, as the laws

Atmospheric Reconstruction with Stagnation Pressure Flight Data from Mars Science Laboratory
, 2017Atmospheric density, pressure, and temperature are reconstructed along the entry trajectory of the 2012 Mars Science Laboratory mission using forebody pressure data from a single pressure sensor that was located near the stagnation point.

Stagnation Pressure, the Bernoulli Equation, and the Steady-Flow Energy Equation [PDF]
International Journal of Mechanical Engineering Education, 2011 The Bernoulli equation is arguably the most commonly used equation in fluid mechanics. For the incompressible, inviscid flow along a streamline, the Bernoulli equation states that the total head of the fluid (the sum of the pressure head, velocity head, and elevation head) is constant.

A Pneumatic Probe for Measuring Spatial Derivatives of Stagnation Pressure
Volume 6: Ceramics; Controls, Diagnostics, and Instrumentation; Education; Manufacturing Materials and Metallurgy, 2019Abstract This paper introduces a pneumatic 9-hole probe which can measure flow angles, stagnation and static pressures, and spatial derivatives of stagnation pressure. It does this through direct measurement at a single location, rather than empirical corrections using measurements at multiple points.

The Effect of Nonuniform Viscosity on Stagnation Point Pressure
Journal of Fluids Engineering, 2011For high Reynolds number flows the total pressure remains constant along stream lines. At low Reynolds numbers the total pressure decreases in a global sense due to the actions of viscosity, but it may increase locally in regions such as stagnation points. Previous studies have considered the case of constant viscosity flow.

Velocity–pressure correlation in stagnation and separation regions on surface-mounted prisms
Journal of Wind Engineering and Industrial Aerodynamics, 1998Experiments are presented for a 1:50 scale model of the Wind Engineering Research Field Laboratory (WERFL) experimental building located on the Texas Tech University campus in Lubbock, Texas. The model was immersed in three different boundary layers generated in the Clemson University wind tunnel.
