1. Numerical study of flow boiling in micro/mini channels
Sammanfattning : Boiling phenomena in micro scale has emerged as an interesting topic due to its complexity and increasing usage in micro electronic and mechanical systems (MEMS). Experimental visualization has discovered five main flow regimes: nucleate boiling, isolated bubbles, confine bubbly flow, elongated bubbly (or slug) flow, and annular flow. LÄS MER
2. Precision cooling for C02 reduction
Sammanfattning : Global climate is adversely affected by increasing emissions of carbon dioxide and other green-house gases. The road transport sector contributes significantly to these emissions. LÄS MER
3. Numerical Modelling of Subcooled Nucleate Boiling for Thermal Management Solutions Using OpenFOAM
Sammanfattning : Two-phase cooling solutions employing subcooled nucleate boiling flows e.g. thermosyphons, have gained a special interest during the last few decades. This interest stems from their enhanced ability to remove extremely high heat fluxes, while keeping a uniform surface temperature. LÄS MER
4. Experimental and Numerical Investigation of the Quenching Process on Rotary Hollow Cylinder by Multiple Impinging Jets
Sammanfattning : The worldwide competitive market on metal products with higher quality in industry has increased the need to implement more advanced and controllable quenching techniques in the hardening stage of the heat treatment process. Moreover, sustainability and energy efficiency are key factors to consider in the development of advanced quenching techniques. LÄS MER
5. Model for activity coefficients and solubilities of Na2CO3 and Na2SO4 in high-temperature solutions
Sammanfattning : Scaling of sodium sulfate and sodium carbonate double salts has long been recognized as a problem in the black liquor evaporation process. These salts are abundant in black liquor and often tend to precipitate on heat transfer areas, thereby significantly decreasing the heat transfer efficiency. LÄS MER
