Deneysel çalışmada, St-37 malzemesinin lazer kesme işleminde yüzey pürüzlülüğünü (Ra) ve kerf genişliğini (KG) etkileyen parametreleri deneysel istatiksel olarak incelenmiştir. Lazer deneylerinin maliyetini azaltmak için parametrelerinin tasarımı Taguchi L32 (21x42) dikey dizilimine göre oluşturulmuştur. parametresi iki farklı frekans (2500 3500 Hz), dört gaz basıncı (0,8, 0,9, 1 1,1 bar) hızı ...

Excessively high temperatures will interfere with the operation of components and damage equipment. The key to fixing this is generate uniform heat dissipation maximize dissipation. This paper proposed a cold plate three S-type multistage Tesla valves (ST-MSTV). Thermal performance was first evaluated flow direction angle. effects channel valve spacing on were then investigated Ansys Fluent sof...

To simulate the effect of free st ream turbulence on turbulent spot formation, experiments were conducted on the interaction of localized three-dimensional disturbances with the harmonic waves in a laminar boundary layer on a flat plate. Experiments conducted in three-dimensional diverging flow (but zero pressure gradient) show, while individually the disturbances decay downstream, their intera...

The dissolution rate is the rate-limiting step for Biopharmaceutics Classification System (BCS) class II drugs to enhance their in vivo pharmacokinetic behaviors. There are some factors affecting rate, such as polymorphism, particle size, and crystal habit. In this study, improve pharmacokinetics of sorafenib tosylate (Sor-Tos), a BCS drug, two habits Sor-Tos were prepared. A plate-shaped habit...
