Thanks to a deep understanding of physical principles, <\/span><b>LENAM engineers<\/b><span style=\"font-weight: 400;\"> are able to adapt and customise these tools to solve highly specific tasks <\/span><b>based on individual customer requirements<\/b><span style=\"font-weight: 400;\">. CFD simulations at LENAM cover a wide range of applications.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">A long-term partner for the automotive industry<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In <\/span><b>the automotive industry<\/b><span style=\"font-weight: 400;\">, CFD simulations are used not only for analysing fluid flow in <\/span><b>oil passages or piping systems<\/b><span style=\"font-weight: 400;\">, but also for more complex processes such as <\/span><b>in-cylinder flow within engines<\/b><span style=\"font-weight: 400;\">. However, LENAM is not just a provider of simulations \u2013 it is a development partner for sustainable and safe vehicles. The company has been collaborating with \u0160koda Auto for over 30 years, and through its connection with <\/span><a href=\"https:\/\/www.aurelcz.eu\/en\/\" target=\"_blank\" rel=\"noopener\"><b>AUREL<\/b><\/a><span style=\"font-weight: 400;\">, it has created a unique combination of simulation, virtual testing, and experimental validation.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Thermal management for batteries and buildings<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">One of today\u2019s key challenges is <\/span><b>thermal management<\/b><span style=\"font-weight: 400;\">, particularly for <\/span><b>batteries and power electronics<\/b><span style=\"font-weight: 400;\">. LENAM focuses on optimising cooling systems \u2013 from airflow design to complex liquid cooling circuits. CFD simulations enable precise optimisation of <\/span><b>heat exchanger performance<\/b><span style=\"font-weight: 400;\"> and the design of optimal cooling concepts. LENAM engineers use advanced simulation models to monitor the thermal behaviour of batteries and optimise both cooling and heating processes. The goal is to maximise lifespan and safety, whether for <\/span><b>electric vehicles, power electronics, or battery storage systems.<\/b><\/p>\n<p><span style=\"font-weight: 400;\">CFD simulations are also used to analyse <\/span><b>airflow in buildings and residential spaces<\/b><span style=\"font-weight: 400;\">, including heat and cooling distribution within rooms. This makes it possible to design <\/span><b>HVAC systems more effectively<\/b><span style=\"font-weight: 400;\"> \u2013 optimising airflow, temperature distribution, and overall system performance to achieve maximum user comfort and energy efficiency.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Aeroacoustics: when airflow becomes audible<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">With the rise of quiet electric motors, aeroacoustics has come to the forefront. Noise generated by airflow often exceeds the noise of the powertrain itself. LENAM\u2019s CFD simulations <\/span><b>help identify sources of unwanted noise<\/b><span style=\"font-weight: 400;\"> \u2013 for example, around side mirrors, A-pillars, fans, blowers, or structural details. Components can be designed from scratch and analysed long before production begins.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Passenger comfort under simulation<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A specialised area includes simulations focused on <\/span><b>human thermal comfort<\/b><span style=\"font-weight: 400;\">. LENAM uses advanced human thermoregulation models to evaluate how the body responds to airflow and temperature conditions. This allows prediction of how different user groups \u2013 such as passengers in buses or aircraft \u2013 will perceive the environment and <\/span><b>enables HVAC settings<\/b><span style=\"font-weight: 400;\"> to be adjusted to suit the widest possible range of users.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">CFD simulations are also widely applied in <\/span><b>turbomachinery, such as turbines and pumps. <\/b><span style=\"font-weight: 400;\">In these systems, they help analyse complex interactions between flow, heat transfer, and mechanical stress, contributing to higher efficiency and reliability.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">The future of CFD: new methods and smarter computation<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Looking ahead, further development is expected, particularly in <\/span><b>linking simulations with real-world operation and machine learning methods<\/b><span style=\"font-weight: 400;\">. These can accelerate repetitive calculations, although the design of new concepts <\/span><b>remains firmly within the domain of engineering know-how<\/b><span style=\"font-weight: 400;\">.
