AI TAKEAWAY

The objective of our study was to evaluate, in a population of Togolese People Living With HIV(PLWHIV), the agreement between three scores derived from the general population namely the Framingham score, the Systematic Coronary Risk Evaluation (SCORE), the evaluation of the cardiovascular risk (CVR) according to the World Health Organization.

Single zone heat release models can effectively be used to model diesel engine combustion process with acceptable degree of accuracy. These models are mainly depend on double Wiebe function which requires as many as six parameters in order to predict the heat release rate (HRR) accurately. However, Wiebe function does not look into the physical air fuel mixing process during the ignition delay (ID) which makes their predictions far from understanding the relation between the HRR and the physical interaction between air and fuel prior to combustion. Whitehouse and Way model covers the physical process since it deals with the mass of fuel injected and the partial pressure of oxygen in which the reaction rate is computed by an Arrhenius type expression. In this work, a strong relationship between HRR and air mass entrained during the ID has been shown. A new single zone heat release model based on Whitehouse and Way model for diesel engine has been developed in order to predict the HRR using standard diesel fuel. The new model has shown to give good results compared to experimental data.
