Dear Mr. Fechner, Thank you for your help first of all. The problem that arises due to the WATER_TIGHT flag is that the condensating water will stay there without any further movement. This means, under these conditions the water is going to accumulate in the air gaps (and won´t be sucked out by the...

Dear Delphin-Team, I am still modelling underground power cables exposed to different soil conditions. Also I am going to investigate the effect air gaps around the protection pipes have onto the water and heat transport (image below). The air gaps´ material properties can be found below. Most impor...

Dear Mr. Fechner,
thank you very much for this quick response.

Then I also have a general question concerning the liquid transport in the gas phase: as long as a material is not assigned "vapour_tight", this transport path is considered in the calculations, right?

Dear Delphin-Team, another question has arisen by analysing some of my models: whenever the cable´s temperature (material: copper) seems to rise above 100 degree Celsius (due to heat loss of e.g. 70 W/m), its temperature stagnates at 100 degree C. When I turned off the water balance, this phenomenon...

Dear Andreas and Mr. Fechner,
I finally had time to implement the adaptations and follow your approaches.

Thank you very much, it helped a lot!

Dear Delphin-Team, I am modelling a 380 kV power cable in a soil body. The power cable is protected by a protection pipe and the space between protection pipe and power cable is filled by air. As far as I know concerning heat transport, heat conduction and heat convection by air is included in the s...

Dear Delphin-Team, I would like to know if there are any manuals or alike published with respect to Delphin. So far I only found "Validierung der Solverimplementierung des hygrothermischen Simulationsprogramms Delphin", "Delphin 6 Output File Specification", and "DELPHIN 6 C...

Hi,
perfect. Thank you very much!

Markus.

Dear Andreas, thank you very much for your quick response! I am well aware that for the calculation of water transport in a medium I also need the water retention curve and the water conductivity. However, before I used Delphin for the first time, I had never heard of a water uptake coefficient Aw. ...

Dear Delphin Team, I am going to analyse heat and water transport in a soil environment in which power cables are bedded. The water uptake coefficient Aw plays a crucial role in correctly calculating the water transport within the soil body, correct? Concerning this parameter, I would like to know w...
