“…The first centrifugal force is perpendicular to the circumferential velocity of the particle and directs towards the impeller outlet, while the second centrifugal force is perpendicular to the relative velocity of the particle and is directed towards the suction surface of the blade. The expressions for the three types of inertial forces are as follows [18,19]: Relative to the liquid, particles have greater mass and inertia, which contributes to a slow decrease in v s,y , the velocity component in y direction, and a slow increase in v s,x , the velocity component in x direction. This leads to a non-collinear relationship between particle velocity and liquid velocity, denoted as v s and v l , respectively, as shown in Figure 1.…”

The erosive wear encountered in some industrial processes results in economic loss and even disastrous consequences. Hitherto, the mechanism of the erosive wear is not clear, especially when the erosive wear is caused by large particles (>3.0 mm) carried by a flowing liquid. Current approaches of predicting erosive wear need improvement, and the optimization of relevant equipment and systems lacks a sound guidance. It is of significance to further explore such a subject based on the relevant literature. The present review commences with a theoretical analysis of the dynamics of large particles and the fundamental mechanism of erosion. Then the characteristics of the erosion of various equipment are explicated. Effects of influential factors such as particle size and properties of the target material are analyzed. Subsequently, commonly used erosion models, measurement techniques, and numerical methods are described and discussed. Based on established knowledge and the studies reported, some expectations for future work are proposed.

“…Several studies have been focused on developing disc protocols to allow an integrated and adequate mixing. On-disc mixing can be passive, just based on the rotation control, based on intrinsic forces as Euler or Coriolis [122][123][124] or by means of control of geometry [125,126]; or can be active based on external perturbations, e.g., compression by external actuators [127] or use of magnetic-beads inside the disc in combination with permanent magnets [128,129]. Several micromixing technologies are discussed in [130].…”

Biosensing on the Centrifugal Microfluidic Lab-on-a-Disc Platform

Lab-on-a-Disc (LoaD) biosensors are increasingly a promising solution for many biosensing applications. In the search for a perfect match between point-of-care (PoC) microfluidic devices and biosensors, the LoaD platform has the potential to be reliable, sensitive, low-cost, and easy-to-use. The present global pandemic draws attention to the importance of rapid sample-to-answer PoC devices for minimising manual intervention and sample manipulation, thus increasing the safety of the health professional while minimising the chances of sample contamination. A biosensor is defined by its ability to measure an analyte by converting a biological binding event to tangible analytical data. With evolving manufacturing processes for both LoaDs and biosensors, it is becoming more feasible to embed biosensors within the platform and/or to pair the microfluidic cartridges with low-cost detection systems. This review considers the basics of the centrifugal microfluidics and describes recent developments in common biosensing methods and novel technologies for fluidic control and automation. Finally, an overview of current devices on the market is provided. This review will guide scientists who want to initiate research in LoaD PoC devices as well as providing valuable reference material to researchers active in the field.
