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.
