We here introduce our cloud chamber which enabled us to grow snow crystals from water vapour under conditions similar to those in natural clouds. The snow crystals grew as a result of water vapour supersaturation as well as due to the interaction of ice crystals and water droplets within the cloud chamber. The cloud chamber, of cylindrical shape wi...
An active fluidization thermal energy storage (TES) called “sandTES” is presented. System design, the fundamental features and challenges of fluidization stability such as mass flux uniformity, powder transport and heat transfer, as well as auxiliary power minimization are thoroughly discussed. The tools and methods for evaluating or simulating the...

Dear experts!
I hope you can help me with this problem! I am using FLUENT to simulate an airflow in a rotationally periodic domain.
k-e realizable, pressure based,coupled, ideal gas law, energy and gravity are the conditions, I chose for my simulation
My domain has a radial pressure outlet at the bottom.
By including gravity a velocity profile with highest velocities at the bottom develops at the the pressure outlet! Can you help me to overcome this problem?!
Thank you for your time!
Hello,
I am trying to define massflow inlet profiles. My profiles should look like a hollow cone spray! ( picture attached)
When trying to implement the mass-flow vectors (x,y,z-direction, massflux), I get two false values...my profile files are correct, so is the allocation to the read-out grid points!
The values between the profile vectors are interpolated...what Idon't know is, if the inlet values are interpolated with the wall values!
Where can I search the problem? Do you think, it's a bug, or can the reason be the flow inside?
I would really appreciate some help!!
kind regards,christian
