摘要： A method for the quantitative acquisition of flow patterns in fluid flows in which a medium (e.g., a gas or a liquid) and the particles contained therein and carried in the flow are set in motion in a transparent flow object. The method provides that a flow object is transilluminated by a laser light fanned out on a plane parallel to the longitudinal axis of the flow object. A scattering of the laser light by the particles is detected by a camera positioned at a right angle to the longitudinal channel axis and moving in the vertical and horizontal directions, and can be analyzed with an analysis unit connected downstream from the camera. The analysis unit is calibrated by quantitatively comparing an image, which has an object-to-image ratio and which is recorded inside the flow object by the camera, to an image having an object-to-image ratio and recorded outside the flow object.

摘要： A method and device for sensing three-dimensional flow structures, which is distinguished in that at least two, preferably three light sheets of a different wavelength or light intensity are produced in a flow measuring field. When a particle carried along by the flow traverses the light sheet, scattered light produced by the particle is optically detected as a particle trace, separately for each light sheet. The detected particle traces of the light sheets are combined into one particle path, and on the basis of the composite particle path, the three velocity components of the flow are calculated.

摘要： A method and a device suitable for carrying out the method are proposed for analyzing and quantifying flows, in particular for the three-dimensional determination of flow velocity components or the three-dimensional visualization of flows in fluids or gases. For this purpose, electromagnetic waves, especially light, are detected, which at least partially emanate from or are scattered by particles that are contained in the detection space and that characterize the flow to be analyzed, the waves being detected using at least one detection device, in the form of two-dimensional images that are recorded in a frequency-selective or frequency-band-selective manner, from which the flow is determined. The illuminating device for this purpose generates at least two, at least approximately parallel light sheets, arranged in spatial succession, generated in temporal succession, having electromagnetic waves of different frequencies or different frequency spectrums, which scan the detection space at least in areas.

摘要： A method and device for analyzing and quantifying flows for the three-dimensional determination of flow velocity components or the visualization of flows in fluids or gases. An illuminating device generates electromagnetic radiation of a predefined color to scan a detection space in the form of light planes arranged spatially one behind the other that are at least roughly parallel, and that are generated temporally one after the other. As a result, electromagnetic waves are generated in the detection space by particles characterizing the flow, and are detected using at least one image detector which records two-dimensional color images. The frequency, frequency spectrum, and/or intensity detected by at the least one of the image detectors is changed by an as a function of time.

摘要： A device is provided for determining at least one parameter of a medium flowing in a line in a main flow direction, e.g., a parameter of the intake air mass of an internal combustion engine. The device includes a part, which is inserted into the line at a predetermined alignment with respect to the main flow direction in such a way that a partial flow of the medium flowing in the line in the main flow direction flows through at least one measuring channel provided in the part in a first direction from an intake of the measuring channel to an outlet of the measuring channel. The device further includes a measuring element situated in the measuring channel for determining the at least one parameter. Between its intake and its outlet, the measuring channel features at least one channel segment in which a mechanism is located that causes flow vortices in this channel segment, whereby liquid droplets and solid particles are advantageously deposited on the inner wall of the channel before they can reach the measuring element.

摘要： Devices for measuring the mass of a flowing medium using a temperature-sensitive measuring element have the disadvantage that considerable measuring errors may occur in the event of a pulsating flow characterized by flow fluctuations. In order to counteract these measuring errors, the device (1) possesses an axially extending measuring duct (33), in which a temperature-sensitive measuring element (20) is accommodated. The measuring duct (33) extends from the inlet mouth (36) to a deflecting duct (34), out of which the flowing medium flows out from an outlet orifice (46) without any axial distance from the inlet mouth (36) and radially underneath the latter. The invention is provided for measuring the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines.

The device has a platelike sensor element which is accommodated in a recess of a sensor carrier, and which with a sensor region that has at least one measuring resistor is exposed to the flowing medium in order to measure its mass. The sensor element is accommodated essentially flush in the recess and is retained in the recess by being glued to a bottom face in the recess. The bottom face of the recess of the sensor carrier has a troughlike indentation, which extends at least partially along the circumference of the sensor element outside the sensor region that has the at least one measuring resistor. The device according to the invention is intended to measure the mass of a flowing medium, in particular for measuring the mass of air aspirated by internal combustion engines.
