Tech­ni­sche Uni­ver­sität Ber­lin - Fac­ulty III - Insti­tute of Pro­cess Engin­eer­ing/ Mech­an­ical Pro­cess Engin­eer­ing and Solids Pro­cessing

Research assist­ant - salary grade E 13 TV-L Ber­liner Hoch­schu­len

part-time employ­ment may be pos­sible

Work­ing field:

The aim of the cur­rent pro­ject and thereby work­ing field is to invest­ig­ate agit­ated particle / fluid sys­tems with focus on flu­id­ized beds in terms of their dynam­ics and heat trans­fer. This is achieved by coup­ling the DEM (dis­crete ele­ment method) with a CFD approach resolv­ing flow around indi­vidual particles based on the Lat­tice-Boltzmann method (LBM). Instead of a sur­face adjus­ted mesh, either Immersed Bound­ary meth­ods (IBM) or inter­pol­ated bound­ary con­di­tions are used on the particle sur­faces as bound­ary con­di­tions. Bound­ary con­di­tions such as IBMs or inter­pol­ated bound­ary con­di­tions are not yet fully estab­lished within coupled sim­u­la­tions involving DEM and LBM. The task is there­fore to eval­u­ate accur­acy and runtime beha­vior. The expec­ted res­ults allow to eval­u­ate the applic­ab­il­ity of cur­rent cor­rel­a­tions for momentum and heat trans­fer and to derive insights for model improve­ments.

Require­ments:

  • suc­cess­fully com­pleted aca­demic uni­versity degree (Dip­lom, Mas­ter or equi­val­ent) prefer­ably in engin­eer­ing sci­ences, e.g. in fluid mech­an­ics, energy, pro­cess, chem­ical or com­pu­ta­tional engin­eer­ing, altern­at­ively also applied math­em­at­ics, phys­ics, com­puter sci­ences; above aver­age res­ults expec­ted
  • interest in engin­eer­ing ori­ented sci­entific numer­ical research
  • know­ledge in the field of sim­u­la­tion meth­ods (e.g. dis­crete ele­ment method, numer­ical flow sim­u­la­tions (CFD) with exper­i­ence/interest in the Lat­tice-Boltzmann method (LBM) or dir­ect numer­ical sim­u­la­tions (DNS))
  • basic pro­gram­ming skills (C, For­tran, Mat­lab)
  • know­ledge in the area of heat and mass trans­fer is help­ful
  • very good know­ledge of at least either Ger­man or Eng­lish (spoken and writ­ten)

How to ap­ply:

Please send your writ­ten applic­a­tion with the ref­er­ence num­ber and the usual doc­u­ments to Tech­nis­che Uni­versität Ber­lin - Der Präsid­ent - Fakultät III, Institut für Prozess- und Verfahrenstechnik, FG Mechanische Verfahrenstechnik und Aufbereitung, Prof. Dr. Kruggel-Emden, Sekr. BH 11, Ernst-Reuter-Platz 1, 10587 Berlin or by e-mail to sekretariat@mvta.tu-berlin.de.
