Fluid analysis for automotive oil lubrication, "Simerics MP+"

Fluid analysis software for positive displacement pumps such as gear pumps and vane pumps! A CFD software specialized for pumps that other CFD software struggles with!

PumpLinx is a fluid analysis software designed to calculate the transient characteristics of various volumetric pumps, compressors, and valves. It is developed based on the thermal fluid analysis software Simerics MP and utilizes all the features of Simerics MP. 【The following fluid analyses are possible】 ■ Free surface flow ■ Flow considering the compressibility of air contained in liquids ■ Pressure pulsation and water hammer effects ■ Coupling of pump flow with the rigid body motion of valves and cam rings ■ Flow in low to medium vacuum conditions ■ Compressible flow (subsonic) ■ Cavitation ■ Time variation of flow field (velocity vector, pressure), flow rate, fluid forces, and torque The biggest strength is the ability to automatically create meshes with clearances in the µm range, which is difficult for other general-purpose fluid analysis software!! Recently, there has been an increase in applications for automotive and construction machinery oil pumps, with examples such as vane pumps for power steering and CVTs, as well as trochoidal pumps for engine lubrication. *There is a lot of information that cannot be posted online. Especially, we encourage you to see the actual mesh creation and movement through a demo presentation!

basic information

(1) Automatic generation of calculation meshes! Even for complex flow paths, automatic generation of calculation meshes is possible with simple button operations. Additionally, for pump chambers that involve rotation/volume changes, high-precision calculation meshes can be automatically generated using a dedicated mesh creation module. It is possible to automatically perform the movement/rotation/deformation of high-precision meshes without tedious tasks. (2) Fluid analysis of various gear pumps is possible! PumpLinx has mesh creation capabilities for various pumps, including different gear pumps, making it easy to perform calculations for a variety of pumps. It also has a mesh creation function for valves, allowing for calculations of flow paths that include valves, and coupled analysis is also possible. (3) More accurate modeling of aeration/cavitation! It includes a high-precision cavitation model, enabling the prediction of non-condensable gas expansion and vapor generation due to cavitation. (4) Calculation of free surface flow As a new feature, the calculation of free surface flow has become possible. It is now possible to analyze oil splashing inside the gearbox and the suction of oil from the oil pan during pump startup.

Applications/Examples of results

PumpLinx is primarily used by automobile manufacturers and automotive-related parts manufacturers in Japan, with numerous achievements in oil pumps used in automotive automatic transmissions (AT) and continuously variable transmissions (CVT), as well as engine oil pumps. Additionally, it has a wide range of implementation results not only in the automotive industry but also globally. Examples of achievements worldwide by the developer can be found at: http://www.simerics.com/testimonials/ There are many cases where companies that have already purchased multiple fluid analysis software domestically, as well as those overseas, have purchased it to improve usability, accuracy, and reduce calculation time in the analysis of volumetric pumps such as gear pumps and vane pumps. A case study on fluid analysis of a vane pump using 'PumpLinx' was published in KYB Corporation's KYB Technical Report No. 53 OCT. 2016.
