“…Also, Voisinet investigated the combined effect of roughness and mass transfer. 9 A series of tests have been undertaken to investigate on the CEV configuration the effect of surface roughness and blowing on turbulent heating, of which further details will be provided in the experimental studies section. Another engineering level assessment is to account for known surface irregularities in the Orion OML that are a result of the attach hardware design for holding the CM on the service module, SM (also shown in Fig.…”

The Project Orion Crew Exploration Vehicle aerothermodynamic experimentation strategy, as it relates to flight database development, is reviewed. Experimental data has been obtained to both validate the computational predictions utilized as part of the database and support the development of engineering models for issues not adequately addressed with computations. An outline is provided of the working groups formed to address the key deficiencies in data and knowledge for blunt reentry vehicles. The facilities utilized to address these deficiencies are reviewed, along with some of the important results obtained thus far. For smooth wall comparisons of computational convective heating predictions against experimental data from several facilities, confidence was gained with the use of algebraic turbulence model solutions as part of the database.For cavities and protuberances, experimental data is being used for screening various designs, plus providing support to the development of engineering models. With the reaction-control system testing, experimental data were acquired on the surface in combination with off-body flow visualization of the jet plumes and interactions. These results are being compared against predictions for improved understanding of aftbody thermal environments and uncertainties.

“…Stevenson's law is characterized by a modification of the slope of the log-law (bilogarithmic form) in which the integration constant C is equal to its non-blowing value. Thereafter, many authors (Danberg 22 , Squire 23 and Voisinet 24 ) showed that the integration constant should be considered as a function of the blowing velocity without questioning the bilogarithmic form. Recently, Vigdorovich 25 proposed a generalization of Stevenson's law of the wall by considering the asymptotic behavior of the velocity profile.…”

“…Despite a significant number of studies on surface roughness and blowing effects, only few works investigated the combined effects of roughness and blowing on turbulent boundary layers (Healzer et al 31 , Pimenta et al 32 , Coleman et al 33 , Schetz and Nerney 34 , Voisinet 24 , Miller et al 35 and Holden 36 ). In most experiments, the effect of blowing for smooth and rough walls exhibits a similar behavior.…”

“…The recent Direct Numerical Simulation (DNS) of Mori et al 37 suggests that Stevenson's law of the wall remains valid in the presence of surface roughness by adding a roughness shift term. Furthermore, Voisinet 24 indicated that the prediction of the combined effects of roughness and blowing is more complex than the superposition of each independent theory. Modeling attempts were proposed by some authors (Healzer et al 31 , Christoph and Pletcher 38 and Ilegbusi 39 ) with varying degrees of success.…”

Modeling of combined effects of surface roughness and blowing for Reynolds-averaged Navier–Stokes turbulence models

2021

View full text Add to dashboard Cite

A new modeling strategy adapted to Reynolds-Averaged Navier-Stokes (RANS) turbulence models is proposed to predict combined effects of roughness and blowing boundary conditions. First, an analysis of experimental data is presented, leading to a specific description of the velocity profile in the logarithmic region of transpired turbulent boundary layers over rough walls. This analysis points out the deficiencies of existing roughness corrections to predict the effect of blowing in the presence of surface roughness. Indeed, these corrections tend to underestimate skin friction coefficients and Stanton numbers with addition of blowing. The failure of existing models derives from an inaccurate estimation of the velocity shift of the logarithmic law given by roughness corrections. Concretely, roughness corrections underestimate the apparent velocity shift of the logarithmic law with blowing. To recover the expected law of the wall, an additional contribution on the velocity shift, characterizing blowing/roughness interactions, is integrated to standard roughness corrections. To that end, a modification of the equivalent sand grain height, adapted to k − ω based turbulence models, is proposed to take blowing effects into account. Furthermore, an extension of Aupoix's thermal correction [B. Aupoix, International Journal of Heat and Fluid Flow 56, 160 (2015)] to blowing is presented to predict combined thermal effects of roughness and blowing. The assessment of the proposed corrections is performed using k − ω Shear Stress Transport (SST) model on a large set of experimental data and proves the relevance of the strategy for incompressible and compressible turbulent boundary layers.

The final report consists of an AIAA and an ASME paper. An experimental investigation was conducted to measure skin friction along the chamber walls of supersonic combustors. A direct force measurement device was used to simultaneously measure an axial and transverse component of the small tangential shear force passing over a non-intrusive floating element. Skin friction coefficients between 0.001-0.005 were measured dependent on the facility and measurement location.
