Virtual prototyping, optimization, on-site fluid technology measurement<\/h3><\/div>

Our partners come to us with unique fluid technology problems that often go beyond quick, industrial solutions. We explore the problem area with numerical flow simulations (CFD), on-site measurements, or our own laboratory experiments. Based on the results, we either immediately propose a solution, or a more detailed investigation, optimization, or research and development phase may follow. <\/span><\/p>\n<\/div><\/div><\/div>

Image processing, data analysis, human vascular system modeling<\/h3><\/div>

Using imaging techniques, we create a digital copy of the vascular system or vascular segment. We can perform various tests, including CFD calculations, on the created geometry, thus enabling us to examine the development of diseases and analyze patient populations. <\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

Stationary pipe network modeling<\/h3><\/div>

We have conducted steady-state pipe network modeling for several partners, using both our proprietary code (the Staci program) and the EPANET software. These calculations analyze the steady-state behavior of pipe networks, including branch flows, flow velocities, nodal pressures, water levels in open channels, water age (residence time), and chlorine concentration distribution. Additionally, our proprietary program runs as background support for our partner\u2019s geographic information system, allowing the immediate assessment of any operational changes to the network through automatic simulation.<\/p>\n<\/div>

Transient pipe network modeling<\/h3><\/div>

At the request of our partner, the Department examined the impact of large consumers on the hydraulic systems of Hungarian cities, focusing especially on transient phenomena in the planned water network. The modeling was divided into two main parts: the sudden shutdown and startup of pumps, and the abrupt cessation of industrial consumption. Special attention was given to the minimum (below atmospheric pressure) and maximum (>10 bar) pressure levels occurring in individual pipelines. In the first case, infiltration (contamination from groundwater), pipe collapse, or even fluid column splitting may occur, while high pressures can lead to pipe bursts. These studies were carried out using computer simulations.<\/p>\n<\/div>

Measurement of hydraulic machine characteristic curves<\/h3><\/div>

At our partners\u2019 sites, many material transport and pumping tasks arise, often carried out using centrifugal or positive displacement machines. The pump characteristic curves H(Q), P(Q), and NPSH(Q) were determined either by on-site measurements or by transferring the pumps to our laboratory at BME. We have tested both small-scale pumps, such as automotive windshield washers, and large industrial pumps, for example those handling reduced crude oil. Our investigations have covered both standard series and custom-made designs.<\/p>\n<\/div>

Pump impeller shape optimization<\/h3><\/div>

The energy consumed by fluid machinery represents a significant portion of the world\u2019s total energy production, so even small improvements in efficiency can lead to substantial global energy savings. Moreover, the geometric design can be optimized not only for water but also for specialized fluids, including those with non-Newtonian rheology. In our related research, we have carried out measurements and numerical simulations to study and optimize the design of pump impellers for water applications.<\/p>\n<\/div>

Contrast agent mixing studies<\/h3><\/div>

In our work for a medical technology company, we investigated how contrast agents with different viscosities mix with blood when introduced into the bloodstream. To model this two-component fluid flow, we used two-dimensional fluid dynamics simulations. Special attention was given to the mixing quality during the injection of the contrast agent through a catheter. Our results helped to understand the factors influencing the mixing process, enabling our partner to improve the quality of medical imaging.<\/p>\n<\/div>

Kayak paddle development<\/h3><\/div>

In elite sports, the technical characteristics of the equipment used can be as important as the athlete\u2019s performance. For our partner, we developed a kayak paddle geometry with improved hydrodynamic properties compared to those currently available on the market. This was achieved through numerical flow simulations combined with laboratory measurements for validation.<\/p>\n<\/div>

Testing of pipes, pipe fittings, and flow measurement systems<\/h3><\/div>

The primary purpose of testing flow components and fittings is to ensure compliance with the applicable national standards and to independently verify the data provided by the manufacturers. In addition, our laboratory performs loss coefficient measurements, as well as leakage and pressure tests, on behalf of our partners.<\/p>\n<\/div>

UV water purifier – disinfection equipment design<\/h3><\/div>

As a result of our research and design work, a custom-made UV water purification system was developed for the Csepel drinking water treatment plant to complement chlorine-based water treatment. We conducted hydraulic and CFD-based dose calculations, as well as our own laboratory measurements to estimate the arrangement and intensity of the UV lamps.<\/p>\n<\/div>
