Bu çalışmada, mikrokarıştırıcıların tasarımı ve performansı üzerine nümerik bir inceleme sunulmuştur. İnceleme, özellikle yüzük tipi elektroosmotik mikrokarıştırıcıların farklı voltaj ve frekanslardaki karıştırma etkinliği ve maliyetleri üzerinde odaklanmıştır. Sonlu elemanlar yöntemiyle yapılan nümerik analizler, karışma performansını belirleyen faktörleri ortaya koymaktadır. Elde edilen sonuçlara göre, mikrokarıştırıcıların tasarımı ve optimize edilmesinde dikkate alınması gereken nümerik bilgileri vurgulanmıştır. Frekansın artışının karışma performansı üzerindeki etkileri incelenmiş ve belirli bir bölgede karışma performansını artırırken, bazı durumlarda negatif etkilere neden olduğu gözlemlenmiştir. Benzer şekilde, voltajın karışma üzerindeki etkileri de detaylı olarak değerlendirilmiş ve doğrudan bir artışın karışma etkinliğini artırdığı belirlenmiştir. Özellikle, geometrik boyutlar, uygulanan gerilim ve frekans gibi parametrelerin karışma performansı üzerinde belirleyici olduğu görülmüştür. 1 ila 5V arası gerilimler ile 4 ve 8Hz frekanslarında analizler gerçekleştirilmiştir. En iyi performans, 4,5V ve 8Hz uygulandığı durumda elde edilmiştir. Bu bağlamda, gelecekteki çalışmalarda, daha karmaşık sistemlerin ve farklı çalışma koşullarının dikkate alınarak daha kapsamlı analizlerin yapılması önerilmektedir.

A Numerical Study of the Mixing Performance of the Electroosmotic Micromixer Design at Different Voltages

Öz

In this study, a numerical investigation on the design and performance of micromixers is presented. The investigation focuses particularly on the mixing efficiency and costs of ring-type electroosmotic micromixers at different voltages and frequencies. Numerical analyses performed using the finite element method reveal the factors that determine mixing performance. According to the obtained results, numerical data that should be considered in the design and optimization of micromixers are highlighted. The effects of increasing frequency on mixing performance were examined, and it was observed that while it enhances mixing performance in a certain range, it can cause negative effects in some cases. Similarly, the effects of voltage on mixing were also evaluated in detail, and it was determined that a direct increase in voltage enhances mixing efficiency. Specifically, parameters such as geometric dimensions, applied voltage, and frequency were found to be decisive on mixing performance. Analyses were conducted at voltages ranging from 1 to 5V and at frequencies of 4 and 8Hz. The best performance was achieved when 4.5V and 8Hz were applied. In this context, it is recommended that future studies consider more complex systems and different operating conditions for more comprehensive analyses.
