In this paper, the bending performances of sandwich panels with corrugated triangular, honeycomb, aluminum foam, pyramidal truss, double sine (DSC), and 3D re-entrant auxetic cores are assessed compared, both experimentally numerically. Three-point experiments were performed on corrugated, truss core identical face-sheets height. The experimental numerical results compared well for honeycomb co...

This study investigates drag reduction capability of naturally occurring-oscillating axial secondary flow (ASF) induced by helical-corrugated surface in Taylor–Couette (TCFHelical) for three values pitch to wavelength ratios (P* = 1, 2, and 3) amplitude ratio(A*) 0.25. As reported Razzak et al. [“Numerical Taylor Couette with longitudinal corrugated surface,” Phys. Fluids 32(5), 053606 (2020)],...

The flow of two superposed viscous fluid layers in a two-dimensional channel confined between a plane and a wavy or indented wall is studied by analytical and numerical methods at arbitrary Reynolds numbers. The interface between the two fluids may exhibit constant or variable surface tension due to an insoluble surfactant. The flow is computed from a specified initial condition using the immer...

The goal of a company is to achieve optimal results and profits so that the continuity can be maintained. purpose this study was analyze production patterns used by Batako Jalan Baru in minimizing additional costs. Data collection techniques are cost analysis using interviews, observation documentation. This research conducted June 2020. three shows most efficient pattern costs on corrugated be...
