Predicting the deposition spot radius and the nanoparticle concentration distribution in an electrostatic precipitator

In magnetic nanoparticle hyperthermia for cancer treatment, controlling nanoparticle is vital for managing heat deposition and temperature elevations in clinical applications. In this study, we first perform a numerical simulation of magnetic nanofluid transport in agarose gel during an injection process and explore the relationship between the spreading shapes of the nanofluid in gel and injection parameters. We also simulate the nanoparticle concentration distribution in tissues after being injected into the extracellular space under various injection parameters. The model consists of two components. One is a particle trajectory tracking model (PTTM) which can predict the deposition rate of nanoparticle on the porous matrix in a single pore structure by using a Lagrangian Brownian Dynamics simulation method. The other one is a macroscale transport model of nanofluid in saturated porous structures. This study provides advanced understanding of nanofluid transport behavior in a porous structure. Our results show that the gap formed surrounding the needle may cause a back flow and can significantly affect the shape of nanofluid spreading. For small-sized nanoparticle (10nm) with zero surface zeta potential, the filtration effect dominates the particle distribution. The effect of other conditions like nanoparticle size, particle surface coating, and physic-chemical properties of carrier fluid on nanoparticle concentration distribution is under study.

In recent years, magnetic nanoparticle hyperthermia has attracted a lot of attentions in cancer treatment due to its ability to confine heat within the tumor with minimal collateral thermal damage to the surrounding healthy tissue.1–4 The success of the treatment using magnetic nanoparticles depends on careful planning of the heating duration and achieved temperature elevations. It has been demonstrated by previous research that the generated volumetric heat generation rate or Specific Absorption Rate (SAR) should be proportional to the nanoparticle concentration distribution in the tumors. The difficulty encountered by bioengineers is that the nanoparticle concentration distribution is often unknown, since the tissue is opaque. Recently, high-resolution microCT imaging technique has been used to visualize magnetic nanoparticle distribution in tumors. MicroCT has been shown to generate detailed 3-D density variations induced by nanoparticle depositions in both tissue-equivalent gels and tumor tissues.5–6 However, experimental studies are still needed to quantify the relationship between the microCT pixel index number shown in the scanned images and the actual nanoparticle concentrations.

Pencemaran udara dapat dikategorikan sebagai pencemaran yang sangat berbahaya dan juga memberikan dampak yang cukup besar bagi lingkungan disekitarnya. Cyclone dan electrostatic precipitator (EP) adalah contoh alat yang dapat mengurangi pencemaran udara di industri semen. Studi ini bertujuan untuk mengevaluasi kinerja cyclone dan EP. Perhitungan kinerja cyclone ditinjau dari jumlah putaran dalam gas dan diameter partikel, dan kinerja EP ditinjau dari kecepatan migrasi partikel dan resistivitas. Metode yang digunakan dalam penelitian ini adalah perhitungan evaluasi dengan menggunakan data aktual. Data tersebut berupa laju alir, densitas, diameter partikel, kecepatan gas inlet, data desain EP dan Cyclone, serta emisi partikulat dan kondisi alat pada saat operasi. Hasil evaluasi menunjukkan effisiensi cyclone sebesar 95,5% dan EP sebesar 98,72%. Kedua nilai efisiensi ini masih memenuhi standar efisiensi alat, yang berarti kinerja cyclone dan EP tersebut masih baik.
