How do Tuna Swim? A #CFD Study 🐟 3D computations show how the finlets function to direct flow toward the tail. The authors were able to compute the effect of finlet–finlet interaction (FFI) and the effect of pitching kinematics on the wake structure and hydrodynamic performance of finlets, and we compare the function of individual finlets with an assembled collective array of finlets present in tuna. 🌎 Paper: https://lnkd.in/euftXAQR 📥 Latest newsletter: https://lnkd.in/d7B7fqA #engineeredmind #technology #engineering #cfd #simulation

Glad to share our new paper published in the journal of Ocean Engineering. In this paper, we identified potential inaccuracies of the IACS CSR rule for predicting ultimate strength of stiffened panels when transverse loads dominate. A correction of this effect is suggested based on a semi-analytical solution using the orthotropic plate theory. The first author is PhD candidate Xintong Wang, who will conclude his PhD soon. Prof. Jørgen Amdahl and I are the coauthors. Enjoy your reading! #stiffenedpanel #buckling #ultimatestrength

Single Variable Thick Plate Buckling Problems Using Double Finite Sine Transform Method https://lnkd.in/daCFU9mR Abstract This paper derives buckling solutions for single variable thick plate buckling problems using the double finite sine transform method (DFSTM). The problem governing partial differential equation (GPDE), originally formulated by Shimpi and others, uses a refined plate theory (RPT) and accounts for transverse shear deformations, rendering it applicable to thick plates. The thick plate is simply supported and subjected to (i) uniform uniaxial compressive load in the x direction. (ii) uniform biaxial compressive load in the x and y axes. The DFSTM was applied to the GPDE, and the problem transformed into an algebraic equation, which was simpler in this case due to the Dirichlet boundary conditions satisfied by the sinusoidal kernel of the DFSTM. Analytical buckling solutions were determined for the two considered cases of uniaxial and biaxial compressive loads in terms of the buckling modes, Poisson’s ratio (m), and thickness (h) to least dimension (a) ratio. Critical buckling loads (Pcr) determined at the first buckling modes agreed with previously obtained Navier solutions for Mindlin, Reddy, and Refined plates. Pcr calculated for ratios of h/a equal to 0.01 converged to the solutions obtained using Kirchhoff-Love plate theory (KLPT), illustrating the applicability of the GPDE to thin and thin plate buckling. Highlights: • The double finite sine transform method was utilized to obtain exact buckling solutions for thick plate problems • The method simplified the problem to algebraic ones since the sinusoidal function satisfies the boundary conditions • The buckling solutions aligned with exact solutions for thick plates Keywords: • Double finite sine transform method • Single variable thick plate • Bending problem • Biaxial buckling • Critical buckling load Journal: https://lnkd.in/dgnvtdte Issue: https://lnkd.in/e--8_6Jf Article: https://lnkd.in/dzgfduQ2 ETJ LinkedIn: https://lnkd.in/d_8SPqAt #Engineering_and_Technology_Journal #UOT #engineering #technology #etj

✨ Excited to share some great news! ✨ Our latest paper, "Modeling Eroded Topography in Masked Abrasive Slurry Jet Pocket Milling," has been published in the International Journal of Mechanical Sciences! 🔍 What’s it about? In #AWJM pocket milling, the use of masks often leads to undesirable erosion near the mask edges—a long-standing issue in the field. While this problem has been known for decades, its underlying mechanism remained speculative. 💡 What did we do? Through innovative experimental techniques and #CFD analysis, we uncovered the mechanism behind this destructive phenomenon. Having identified the roots of the problem, we then designed and tested experimental techniques in terms of tool path strategies to eliminate undesirable erosion and fabricate micro pockets with uniform depth using masked AWJM.

How to embed a small specimen in a well of low melting agarose and Phytagel and mount it on a stage for imaging ?  The architecture of PHASEVIEW Alpha3 light sheet microscope using a fluorescence microscope stand as a detection unit allows it to adapt to any experiment setting. Follow these steps : - Use T-spike holder  - Put forming mold on top of holder - Fill with liquid - 0,8 % phytagel - Insert well-shaping mold  - Wait for phytagel to solidify - Remove shaping molds - Add specimen and medium to well - Close with low-melting agarose drop.  - Insert mold into sample chamber - Adjust sample orientation  - Place sample chamber on translating stage More information in this tutorial :
