Shear Performance

This paper reports the experimental results to evaluate in-plane shear performance of insulated concrete sandwich panel (ICSP) with glass fiber-reinforced polymer (GFRP) grid shear connectors. The variables considered in this study are the grid size (35 and 53mm) of GFRP shear connectors and the types of insulation (expanded polystyrene, EPS and extruded polystyrene with special slots, XPSS). For loading in-plane shear force to interface between inner and outer wall of ICSP system, the ICSP specimens were supported vertically at the bottom edge of the two concrete outer walls by steel blocks. The test results indicate that ICSP with XPSS developed higher shear flow strengths in ICSP with EPS when 35mm spacing of GFRP grid is used. Also, the test results indicated that as the grid spacing of GFRP shear connector decreases, the shear flow strength of ICSP with XPSS insulation was higher, but the shear flow strength of ICSP with EPS insulation was lower.

Removing inclusions from the melt is an important task in metallurgy with critical impact on the quality of the final alloy. Processes employed with this purpose, such as flotation, crucially depend on the particle size. For small inclusions, the aggregation kinetics constitute the bottleneck and, hence, determine the efficiency of the entire process. If particles smaller than all flow scales are considered, the flow can locally be replaced by a plane shear flow. In this contribution, particle interactions in plane shear flow are investigated, computing the fully resolved hydrodynamics at finite Reynolds numbers, using a lattice Boltzmann method with an immersed boundary method. Investigations with various initial conditions, several shear values and several inclusion sizes are conducted to determine collision efficiencies. It is observed that although finite Reynolds hydrodynamics play a significant role in particle collision, statistical collision efficiency barely depends on the Reynolds number. Indeed, the particle size ratio is found to be the prevalent parameter. In a second step, modeled collision dynamics are applied to particles tracked in a fully resolved bubbly flow, and collision frequencies at larger flow scale are derived.
