This blog discusses the causes of cavitation, and current methods of determination of valve cavitation and how Computational Fluid Dynamics (CFD) will help in minimizing it. Briefly, it presents a short study on the identifying onset of valve cavitation on a DN100 globe valve using a cloud-based valve CFD software by simulationHub.
We are exhibiting at 2019 Valve World Americas Expo and Conference schedule on 19 and 20th June 2019. Visit simulationHub booth 1445 to know about our autonomous valve CFD product and get an exciting hands-on experience of our Machine Learning and Augmented Reality apps for valve design.
Occupant thermal comfort is of prime importance when we evaluate the effectiveness of any building HVAC system. Achieving a desired thermal comfort is challenging as it depends on many factors including ducting layout, supply, and returns arrangement, occupant density, occupant activity, and external environmental conditions. There is not a single perfect tool to quickly and easily estimate the comfort conditions for different design configurations and scenarios. simulationHub is working on a state-of-the-art thermal comfort app which will change the way HVAC systems are designed and evaluated. This blog gives sneak peek into what is this app and how this is going to be a great tool for HVAC designers, consulting firms and the end users.
Thermal comfort is an important aspect in representing human satisfaction, which is defined as the condition of mind which expresses satisfaction with the thermal environment by ASHRAE. It means that a person feels neither too cold nor too warm. The idea of this blog is to provide a detailed discussion of various thermal comfort indices and the role of CFD in evaluating thermal comfort in occupied spaces.
Butterfly valves are a primary selection in case of shut-off application. It is known for its high-performance in fluid flow industry. Actuators are a very crucial part of the complete valve assembly and costs about 30 to 40% of total package cost. The selection of actuator depends on many factors, but most importantly on torque requirement. This blog discusses the hydrodynamic torque behavior of the double offset butterfly valve. Using our Control Valve Performer app, a comparative study is done to understand the hydrodynamic torque and how it behaves in case if flow direction is reversed. Get the insight into butterfly valve hydrodynamic torque for seat and shaft side flow.
Only 1 out of 100 CAD designer uses Computational Fluid Dynamics in his design workflow. High cost and complex design of CAE software have been the key reason for designers not to use CAE in their design process. Simulation software has a tedious workflow and has a high degree of learning curve. simulationHub is built with the designer as a focal point. At the inception stage of simulationHub, we have decided that appification is the way forward. That is the way to democratize CFD. Not for many, but for few, appification is bit difficult concept to understand. In this blog, Chaitanya explains this concept in a unique way. It’s a fun to read but at the same time throws a light on why appification is the way forward.
