Strong fluid analysis software for oil pumps 'Simerics MP+'

Simulate the flow characteristics of positive displacement pumps such as gear pumps and vane pumps! A CFD software specialized for pumps that other CFD software struggles with!

Simerics MP+ is a fluid simulation tool designed to calculate the transient characteristics of various volumetric pumps, compressors, and valves. It is developed based on the thermal fluid simulation tool 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 pulsations 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 vectors, pressure), flow rate, fluid forces, and torque The greatest strength is the ability to automatically create meshes even for clearances in the µm range, which is difficult for other general-purpose fluid analysis software!! Recently, there has been an increase in achievements with oil pumps for automotive and construction machinery, such as vane pumps for power steering and CVTs, and trochoidal pumps for engine lubrication. *There is a lot of information that cannot be posted online. Especially, please see a demo presentation for the actual mesh creation and movement!!

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 involving rotation/volume changes, high-precision calculation meshes can be automatically generated using a dedicated mesh creation module. It is possible to automatically execute the movement/rotation/deformation of high-precision meshes without tedious tasks. (2) Fluid analysis of various gear pumps is possible! Simerics MP+ 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, making it possible to predict the expansion of non-condensable gases and the generation of vapor due to cavitation. (4) Calculation of free surface flow 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

Simerics MP+ is primarily used by automobile manufacturers and automotive-related parts manufacturers in Japan, with numerous achievements in applications such as oil pumps used in automotive ATs and CVTs, as well as engine oil pumps. Additionally, it has a wide range of implementation achievements 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 chosen to purchase it for the ease of use, accuracy improvement, and reduction of computation 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 'Simerics MP+' was published in KYB Corporation's KYB Technical Report No. 53 OCT. 2016. 【Prediction of Vane Pump Characteristics through CFD Analysis】 https://www.kyb.co.jp/technical_report/data/no53j/03_technology_explanation_01.pdf
