Leib­niz-Insti­tut für Agrar­tech­nik und Bio­öko­no­mie e.V. (ATB)

The Leib­niz Insti­tute for Agri­cul­tural Engin­eer­ing and Bioeconomy is a pion­eer and a driver of bioeconomy research. We cre­ate the sci­entific found­a­tion to trans­form agri­cul­tural, food, indus­trial and energy sys­tems into a com­pre­hens­ive bio-based cir­cu­lar eco­nomy. We develop and integ­rate tech­niques, pro­cesses and man­age­ment strategies, effect­ively con­ver­ging tech­no­lo­gies to intel­li­gently cross­link highly diverse bioeco­nomic pro­duc­tion sys­tems and to con­trol them in a know­ledge-based, adapt­ive and largely auto­mated man­ner. We con­duct research in dia­logue with soci­ety - know­ledge-motiv­ated and applic­a­tion-inspired.

Doc­toral Researcher (m/f/d) (65 %)

For the basic research pro­ject “Determ­in­a­tion of air exchange rates in nat­ur­ally vent­il­ated barns — Val­id­a­tion of pre­dic­tion Mod­els 2.0”, fun­ded by the Ger­man Research Found­a­tion, in the work­ing group “Barn cli­mate and emis­sion mod­el­ling”

Working field:

The barn cli­mate and emis­sions mod­el­ling work­ing group devel­ops, adapts and val­id­ates empir­ical and mech­an­istic mod­els for describ­ing and pre­dict­ing tem­per­at­ure dis­tri­bu­tion and air qual­ity in nat­ur­ally vent­il­ated barns and pol­lut­ant trans­port pro­cesses in con­nec­tion with live­stock farm­ing. The mod­els are fur­ther used to eval­u­ate options for adapt­ing barn sys­tems to cli­mate change and redu­cing emis­sions.
The math­em­at­ical mod­el­ling (i.e., com­pu­ta­tional fluid dynam­ics mod­el­ling, clus­ter­ing and regres­sion ana­lysis) in the pre­de­cessor pro­ject “BeLuVa” ( provided ini­tial insights into how bound­ary con­di­tions influ­ence the air exchange rate in indi­vidual animal accom­mod­a­tion areas and local con­cen­tra­tion ratios of tar­get and trace gases. Based on this, the basic under­stand­ing of the influ­ence of the wind dir­ec­tion shall be expan­ded and tip­ping points iden­ti­fied at which a change in the wind dir­ec­tion sig­ni­fic­antly changes the flow. Another goal is the refine­ment of the para­met­ric mod­els derived in BeLuVa for local air exchange and gas bal­an­cing accur­acy. Model res­ults are cross-val­id­ated with meas­ure­ments in a large bound­ary layer wind tun­nel and in the real barn.
