Low salinity water flooding is a promising enhanced oil recovery technique that has been observed, in experiments over range of scales, to increase production by up 14% some systems. However, there still no way reliably predicting which systems will respond favourably the technique. This shortcoming partly because relative lack pore scale observations low flooding. led poor understanding how me...

Catalytic converters are used for minimizing the release of pollutants to the atmosphere. It is during the warm-up period that hydrocarbons are seen to be released in appreciable quantities from these converters. In this paper the conversion of a fast oxidizing hydrocarbon propylene is analysed using two numerical methods. The quasi steady state method assumes the accumulation terms to be negli...

1 One-dimensional Unsteady Inviscid Flows We consider now the problem of unsteady flow in one-dimension under the inviscid assumption. We have a rigid tube with cross-sectional area A(x), and we assume that all the variables (x-component of velocity u and all the thermodynamic state variables) are functions of x and t only. The governing equations are: A Dρ Dt + ρ ∂(uA) ∂x = 0, (1a) ρ Du Dt + ∂...

An unsteady flamelet/progress variable model has been developed and formulated as an extension of the steady flamelet/progress variable model. For this model, a large number of unsteady laminar flamelet simulations is performed for various conditions, and solutions are recorded as function of time. From this, a flamelet library is generated, which provides the filtered quantities of all scalar ...
