    摘要： A method of performing acoustically enhanced sedimentation in a sample of a suspension comprising particles and a fluid is provided. The method comprises the steps of: i. introducing a volume of the sample into an accumulation zone of a microfluidic cavity; ii performing the substeps of: a. during a first time period: subjecting the volume to an acoustic standing wave configured to cause the particles in the volume to accumulate in at least a first region of the volume; b. during a second time period: subjecting the volume to a gravitational field affecting the particles and the fluid so that the particles accumulated in the at least one first region sediment in a first direction in relation to the direction of the gravitational field, thereby removing particles from the volume; and iii. moving the volume in a second direction opposite the first direction by introducing a subsequent volume of the sample into the accumulation zone of the microfluidic cavity. An acoustofluidic system is also provided.

    摘要： A screen assembly includes a frame having an outer perimeter and at least one inner support member, and at least one smooth surface affixed to the frame, where the smooth surface(s) have perforations. The frame may include a plurality of contact points extending upward from a top surface, and at least one smooth perforated screening surface is affixed to the plurality of contact points on the frame. In some cases, the smooth surface comprises a perforated region and an erosion resistant region. Also, the perforations may have a shape that includes one or more corners. The smooth surface may be a perforated metal foil, sheet metal, and the like. Perforations may be apertures having one or more opening area sizes across the span of the screen assembly.

    摘要： A fluid device includes: a flow main body including a side wall along a first axis and configured to flow a fluid from an inflow portion provided at one side of the first axis toward an outflow portion provided at the other side of the first axis; a plate provided at the other side of the first axis of the flow main body and having a first surface intersecting the first axis; a standing wall extending along the first axis from the first surface toward the one side of the first axis and having a length along the first axis shorter than the side wall; and an ultrasonic element disposed at an outer side of a collection region of the plate and configured to transmit an ultrasonic wave along the first axis when the standing wall and a region surrounded by the standing wall on the first surface are defined as the collection region.
