Yavuz, F. (author), van Tilburg, T. (author), David, P. (author), Spruijt, M. (author), Wildenborg, T. (author), TNO Bouw en Ondergrond (author)Carbon dioxide Capture and Storage (CCS) is a promising contribution to reduce further increase of atmospheric CO2 emissions from fossil fuels. The CCS concept anticipates that large amounts of CO2 are going to be stored in the subsurface for the long term. Since CCS is a rather new technology, uncertainties related with the future evolution of...article 2009

(author)Collision of injected fuel spray against the cylinder liner (wall-wetting) is one of the main hurdles that must be overcome in order for early direct injection Premixed Charge Compression Ignition (EDI PCCI) combustion to become a viable alternative for conventional DI diesel combustion. Preferably, the prevention of wall-wetting should be...conference paper 2009

Leskens, M. (author), de Kruif, B. (author), Belfroid, S.P.C. (author), Smeulers, J.P.M. (author), Gryzlov, A. (author), TNO Industrie en Techniek (author)Multiphase flow meters are indispensable tools for achieving optimal operation and control of wells as these meters deliver real-time information about their performance. For example, multiphase flow meters located downhole can improve the production of multilateral and multizone wells by timely allocating the zone where a gas or water cone...conference paper 2008

(author), TNO Industrie en Techniek (author)A strong increase in gas inflow due to gas coning and the resulting bean-back because of Gas to Oil Ratio (GOR) constraints can severely limit oil production and reservoir drive energy. In this paper we will use a coupled reservoir-well model to demonstrate that oil production can be increased by using controlled inflow from a gas cone as a...conference paper 2008

(author), TNO Defensie en Veiligheid (author)Ramjet propulsion is often proposed for airbreathing applications with speeds higher than Mach 3. However, for speeds higher than Mach 5, the performance of a ramjet drops significantly and the scramjet is the preferred option. The shock-induced combustion ramjet, or shcramjet, is also an interesting alternative at higher flight speeds. Its...conference paper 2008
