Winter Is Coming - A sneak peek into the upcoming app for Occupant Thermal Comfort

Wednesday, January 30, 2019

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.

Role of CFD in evaluating occupant thermal comfort

Friday, January 25, 2019

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.

Understanding torque behavior of the double offset butterfly valve

Tuesday, January 15, 2019

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.

simulationHub, where CFD is served on a platter!

Monday, December 17, 2018

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.

Building a Machine Learning Valve Design App

Wednesday, May 23, 2018

Machine learning (ML) techniques are now widely being used in almost all areas of application. Six months back, CCTech Research started investigating how we may use ML in the area of Design of Mechanical Systems. One of the key application we were particularly interested is in Control Valve industry. simulationHub's Control Valve Performer app is already calculating valve performance within minutes compared to weeks in traditional CFD way. But one still yearns for a solution that could predict the flow performance in less than 5 seconds. The machine learning app developed by CCTech research team is now able to predict the value performance within seconds. Read more about the app, what went into creating the app and the app workflow.
