6. Laser metal fusion and deposition using wire feedstock : Process modelling and CFD simulation
Sammanfattning : Laser metal fusion is widely used in production technology to manufacture parts, as in welding, cladding, and additive manufacturing. In this study, conduction mode laser metal fusion is applied without and with metal deposition from a wire feedstock. LÄS MER
7. Computational fluid dynamics for detention tanks : simulation of flow pattern and sedimentation
Sammanfattning : .... LÄS MER
8. Multiscale Simulation Methods for Thermoelectric Generators
Sammanfattning : Rising energy prices and greater environmental awareness, along with stringent emissions legislation, in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied here, is heat recovery from exhaust gases using thermoelectric generators. LÄS MER
9. Detached Eddy Simulation for Aerospace Applications
Sammanfattning : With the continuous growth in air traffic that we see nowadays, comes an increase in the requirements needed to be satisfied in order to certify an aircraft for operation. These stricter regulations affect aspects such as CO2 emissions, sound pollution and so on, pushing manufacturers to aim for lighter, more efficient, more robust designs. LÄS MER
10. Large eddy simulation of combustion using linear-eddy subgrid modeling
Sammanfattning : As emissions regulations are getting stricter and efficiency requirements of internal combustion engines (ICE) are increasing, different concepts to improve combustion are being investigated. For example lean stratified premixed combustion, homogeneous charge compression ignition (HCCI), use of more exhaust gas recirculation (EGR) to reduce NOx etc. LÄS MER
