𝑪 𝒃 - Mass flow model for gases in high pressure range
13.03.2024 Results indicate that the 𝑪, 𝒃 model is more suitable than the 𝑲 𝑽 value when it comes to gases, in particular for describing mass flow through a valve with gaseous hydrogen.
By Lucian Pasieka
For many decades now, valves have been designed using the 𝑲 𝑽 value . This article shows the development path from the 𝑲 𝑽 value for water and gases to the 𝑪, 𝒃 model for gases, which is already used with real gas data for high pressure hydrogen applications . Results indicate that the 𝑪, 𝒃 model is more suitable than the 𝑲 𝑽 value when it comes to gases, in particular for describing mass flow through a valve with gaseous hydrogen. The 𝑪, 𝒃 values are also beneficial for system simulation and for the design of complete systems, e.g. refueling stations for hydrogen car or buses.
