Numerical Investigation Of Non-Newtonian Emulsion Formation At Microfluidics T-Junction

W. V. Loong [1]
[1] SEGi University, Malaysia

The main focus of the present study is the parametric investigation of the influence of viscosity on breakup dynamics of the non-Newtonian sodium carboxymethylcellulose (CMC) droplets. It presents the numerical simulations of the fluid dynamics of CMC droplets with shear-thinning ... En savoir plus

Numerical Analysis of the Optimal Design Parameters of a Thermoelectric Microfluidic Sensor

S.M.I. Bari¹, L. G. Reis¹, G. G. Nestorova¹
¹Louisiana Tech University, Ruston, LA, USA

The design of highly-sensitive thermoelectric microfluidic sensors for the characterization of biochemical processes is an important area of engineering research. This study reports three-dimensional numerical analysis of the critical design parameters of a continuous-flow biosensor with ... En savoir plus

A Multiscale Model of the Bipolar Electrode - SDS Adsorption on Stainless Steel

Hörmann, Johannes (何约翰) [1], Meng, Yonggang (孟永钢) [1],
[1] State Key Laboratory of Tribology, Tsinghua University, Beijing, China

In solution, sodium dodecyl sulfate (SDS) (structure shown in Fig. 1) can form a boundary film on metal surfaces. Previous studies have extensively investigated the characteristics of such surfactant films experimentally [1][2][3]. A dependency of SDS surface concentration and film ... En savoir plus

Simulation of a Dynamic Scraped Surface Heat Exchanger for Non-Newtonian Fluids

S. Birla [1],
[1] ConAgra Foods, Omaha, NE, USA

Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. One of the factor posing difficulties to heat transfer is viscosity. Highly viscous fluids tend to generate ... En savoir plus

Dynamic Observation of Magnetic Particles in Continuous Flow Devices by Tunneling Magnetoresistance Sensors

A. Weddemann[1], A. Auge[1], F. Wittbracht[1], C. Albon[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We ... En savoir plus

CSRR-Based Microwave Sensor for Measurement of Blood Creatinine Concentration Levels

Z. Ramsaroop [1], S. Rocke [1], N. Gayapersad [1], J. Persad [1],
[1] Department of Electrical and Computer Engineering, The University of the West Indies, St. Augustine Campus, Trinidad and Tobago

Non-communicable diseases (NCDs) have globally become a prevalent problem, accounting for more than 60% of the mortality worldwide. NCDs impose socioeconomic consequences to low-income countries as 80% of NCD deaths occur in such countries [1, 2]. The World Health Organization has ... En savoir plus

I. Kuehne [1], N. Philippin [1], M. Michatz [2], A. Frey [2],
[1] Heilbronn University of Applied Science, Kuenzelsau, Germany
[2] University of Applied Science, Augsburg, Germany

INTRODUCTION: Microfluidics, as a crucial technology of recent years, enables numerous applications for Point-of-Care-Testing such as Lab-on-Chip-Systems (LOC) or Micro-Total-Analysis-Systems (µTAS) and is exceptionally well-suited for cell sorting or DNA trapping. Especially the ... En savoir plus

Finite Element Analysis of Planar Microcoil Based Induction-balance Magnetic MEMS Sensor

Krishnapriya S¹, Suja K J², Rama Komaragiri³
¹Department of ECE. Muthoot Institute of Technology, India
²NIT Calicut, Calicut, Kerala India
³Bennett University, Greater Noida, Uttar Pradesh, India

Two transmitting planar microcoils (TX1, TX2) and one receiving microcoil (RX) are employed as shown in Fig.1 formed in induction-balance configuration. RX-Coil is positioned in such a way to achieve primary field suppression in RX-Coil’s region. Meaning, a magnetic cavity is created in ... En savoir plus

Coupling Non-Newtonian Fluid Flow and Heat Transfer Inside a Scraped Surface Heat Exchanger

A. Plana-Fattori[1], D. Flick[1]
[1]UMR 1145 Ingénierie Procédés Aliments, INRA, AgroParisTech, Université Paris-Saclay, France

Scraped-surface heat exchangers (SSHEs) handle products that are viscous, that contain particles, and that tend to deposit on the heat transfer surface. The rotating scraper blades continuously remove any deposition on the heating or cooling surface, thereby maintaining the efficiency of ... En savoir plus
