  • Fuel Homogenization

    The structure of the financial expenses of automotive businesses and boiler plants is quite varied, though it still allows to identify the main expenditures. First of all, it is the fuel, which accounts for no less than 40% of all costs. Fuel homogenization devices are designed to increase the quality of combustion, thereby saving resources. Homogenized fuel features good performance, ...

  • Homogenous mixing for shortening of composting processes - Case Study

    Various treatment processes are used today for manufacturing compost, of which two are of particular interest in terms of mixing and treatment technology. They are open composting and container composting. In both cases e.g. sewage sludge (wet and dry), chopped paper, loppings, green waste, and sawdust are pre-mixed with the possible addition of small amounts of active substances. The task of ...

  • Application of a soft computing technique in predicting the percentage of shear force carried by walls in a rectangular channel with non-homogeneous roughness

    Two new soft computing models, namely genetic programming (GP) and genetic artificial algorithm (GAA) neural network (a combination of modified genetic algorithm and artificial neural network methods) were developed in order to predict the percentage of shear force in a rectangular channel with non-homogeneous roughness. The ability of these methods to estimate the percentage of shear force ...

  • Spatial and temporal characterization of climate at regional scale using homogeneous monthly precipitation and air temperature data: an application in Calabria (southern Italy)

    In the present study, an approach for a climate characterization based on a statistical analysis of monthly precipitation and temperature data is presented. First, the original database (1916–2010) was homogenized and a geostatistical analysis was carried out to characterize the monthly mean distribution of the two variables in the study area. Then, temporal change of precipitation and ...

  • Exergy analysis of natural gas/DME combustion in homogeneous charge compression ignition engines (HCCI) using zero–dimensional model with detailed chemical kinetics mechanism

    In the present work, a single zone combustion model with detailed chemical kinetics is developed to study the effect of dimethyl ether (DME) concentration on the combustion of natural gas from second law point of view in a homogeneous charge compression ignition (HCCI) engine. The code can predict all exergy terms in the cylinder with crank angle during a closed cycle. The chemical kinetics ...

  • Quantitative analysis of APIs in blending mixtures and tablets

    Introduction Pharmaceutical tablets consist of an Active Pharmaceutical Ingredient (API) with excipients including fillers, binders, and lubricants. In tablet manufacturing, blending is the process where APIs and various excipients are blended together to form a homogenous mixture. The blending process control is very important for final tablet quality, and yet blending process control ...

  • Markov chain applications in modelling facility condition deterioration

    Condition states of civil infrastructure such as pavements and bridges are usually indexed on discrete scales. Historical condition data is modelled using Markov chain to estimate transition probabilities from one condition state to another, the rate of change and the time spent in any given state. The usefulness of such models is a function of the completeness of the available records and ...

  • Application of reactor net models for the simulation of gas-turbine combustor emissions

    The work deals with the evaluation of applicability of reactor net models and different reaction mechanisms for the predictions of emission characteristics of aero-engine combustors operating both in diffusion and in homogeneous burning modes. It is shown that the accuracy of the calculations of emission indices for NO x , CO and unburned hydrocarbons (UHC) is dependent strongly on the applied ...

  • Blending process in everyday life

    Liquids mixing processes are extensively relates to human life. For example we could meet these processes in the laboratory chaotic advection researches, in oil processing branches, chemical, industrial and even in the food industry. Passing speed, quality of a compound and expense of energy are undoubtedly one of defining factors in developing process of compounding system. Despite that ...

  • Optimal pricing non-homogeneous market with network externalities

    The paper analyses the options open to monopoly firms that sell software or internet service. We consider customers who have different reservation prices that are rectangularly distributed. The monopoly in general undertakes sustainable price discrimination between customers by producing two versions of the product, basic and advanced, where a zero price is charged for the lower quality product ...

  • Sewage sludge solubilization by high-pressure homogenization

    The behavior of sludge solubilization using high-pressure homogenization (HPH) treatment was examined by investigating the sludge solid reduction and organics solubilization. The sludge volatile suspended solids (VSS) decreased from 10.58 to 6.67 g/L for the sludge sample with a total solids content (TS) of 1.49% after HPH treatment at a homogenization pressure of 80 MPa with four ...

  • Artificial neural network (ANN) modeling of dynamic effects on two-phase flow in homogenous porous media

    The dynamic effect in two-phase flow in porous media indicated by a dynamic coefficient τ depends on a number of factors (e.g. medium and fluid properties). Varying these parameters parametrically in mathematical models to compute τ incurs significant time and computational costs. To circumvent this issue, we present an artificial neural network (ANN)-based technique for predicting ...

  • Homogeneous, heterogeneous and biological oxidation of iron(II) in rapid sand filtration

    Homogeneous, heterogeneous and biological oxidation may precipitate iron(II) as iron(III) hydroxides. In this paper we evaluate the conditions under which each of these processes is dominant in rapid sand filtration (RSF). It is demonstrated that in the presence of iron(III) hydroxide precipitates homogeneous oxidation is negligible compared with heterogeneous oxidation. As soon as iron oxidizing ...
