Engineering & Computational Mechanics Center

The Engineering & Computational Mechanics Center (ECMC), located at the Rotem Industrial park, was reestablished on January 2007 to serve the industry in Israel and abroad. The center belongs to Rotem Industries and employs experts and engineers with vast experience in: system design, numerical simulation based on modern software and evaluation by experiments.
 
The Center can provide full systems and/or sub-components design, having well defined data base, up to a complete manufacture product file. In addition, the ECMC is capable of dealing with projects, in which data base is uncompleted and requires data completion by experts in numerical calculations and/or experiments performance with the aim of minimizing knowledge gaps.

The ECMC uniqueness lays in its ability to activate expert skills in order to deal with engineering knowledge gaps, including subjects which are not in the classic literature. The Center owns commercial first row software, enabling calculations and simulation performance in diverse subjects such as: fluid mechanics, heat & mass transfer, strength of materials, general mechanics, metallurgy and coupled Problems which combines more than one of the above. The center can backup all calculations and simulations with experiments in all ranges in the modern physics, conducted on an advanced international high standards infrastructure.

Modern companies find it today more efficient to keep a small core of key full time staff and subcontract work on an 'as required' basis. This keeps overheads down and reduces depreciation on expensive under-utilized computer equipment. It is more efficient to use a reliable company of known abilities that know your system and has well trained staff with state of the art equipment. - This is what we offer.
 
 
The ECMC is operated and managed by a group of experts and engineers supported by a variety of experienced specialist groups from various discipline.
 

The ECMC Capabilities

  1. Standards and nonstandard pressure vessels design such as: High temperature-pressure air solar receivers and space simulation vacuum chambers.
  2. Accumulate experience and knowledge of over 20 years, in performing numerical analyzes with final elements and final volumes with expert software. The center owns a variety of commercial expert software among them: FLUENT/Ansys for CFD, heat and mass transfer, and strength of materials, COMSOL Multiphysics for Multidisciplinary problems, and in addition to these software, the center relies on own built calculation models using MATHCAD.. In this area the center has a common activity with the mechanical engineering department of Ben-Gurion University of the Negev (BGUN).
  3. Calculation for characterizing thermal strain field in metallic and brittle materials such as: Quartz windows design for application in solar collector for different environment conditions. Such windows were designed to withstand different working condition, and their performances were proved in practice.
  4. Measuring physical properties of materials in numerous fields such as: thermal properties of materials (thermal conductivity, thermal diffusivity, specific heat est...), Thermal radiation (emissivity, absorptivity on and between surfaces) and mechanical and strength properties (expending coefficient, yield strength, and hardness).
  5. Develop and design advanced thermal isolation such as: vacuum radiation shields or another gas environment shield at different pressures, for regulation of required isolation level.
  6. Develop and produce heat removal tools, among them thermosiponic heat pipes and heat pipes with capillary wick, for working in negative angle cases.
  7. Design and perform fluent experiments, combining all heat transfer mechanism, including two phase flow, boiling and condensing.
  8. Transportation systems Design, including environment and field tests performance such as: shocks and vibrations.

The following examples are part of major projects conducted by Rotem industries, in which the design included engineering knowledge gap completion, based on advanced calculations backed up with experiment results. These systems and sub systems are working for a long time in the market and still proving success and high reliability.
  1. Space conditions simulation by vacuum chamber system for MABAT-IAI

Satellites and their components lunched to the space are being exposed to fundamental different conditions than on earth. The air is much more diluted almost as high vacuum surrounding. The air temperature varies extremely, part of the day high due to the sun radiation and very low on the other part.

Examination of the satellite and its accessories on earth conditions cannot be a proof for their reliable functioning in space. Therefore, testing chambers has been developed for the entire satellite and fore its accessories, in which the condition are as much as possible close to the working conditions in space.

The chamber provides high vacuum (down to 10-6 bar) and a controlled ambient temperature between -190oC and up to 300oC.

The system contains: the testing chamber, vacuum system, thermal system and the control system. The system enables convenient accessories charge and discharge, enables a large variety of measurements and a full control on the experiment process.

  1. Sun Tower Project for solar Energy collection in The Weitzman Institute

A Solar Thermal Demonstration Power Plant with a High Temperature central Receiver (HTR) was built at the Weizmann Institute of Science (WIS), Rehovot, Israel, as a joint project of Rotem Industries, Ormat industries, WIS and the Boeing Company. Solar tests were carried out successfully throughout 2001 in order to demonstrate the feasibility of a large-scale central solar receiver.
