“…When keeping dependent of fossil fuels, food production remains a major contributor to anthropogenic GHG emissions. Therefore, trends for using renewable energies is advocated by many and refer to various facets including improving the energy efficiency of food processes, adopting hydrogen energy in transportation and farm tractors (Salvi and Subramanian 2015), extending the use of electricity (Moreda et al 2016) and adopting an increased use of biofuels (Guo et al 2015;Matuszewska et al 2016) including for hydrogen production. However, biofuels bring to the scene the land use competition between food crops and energy crops, which remains a non-solved problem despite some optimism (Rathmann et al 2010;Valentine et al 2012).…”

Population growth, increasing demands for food, ever-growing competition for water, reduced supply reliability, climate change and climate uncertainty and droughts, decline in critical ecosystems services, competition for land use, changing regulatory environments, and less participatory water resources governance are contributing to increasing difficulties and challenges in water resource management for agriculture and food. The need for sustainable food security for our global population and the need for preserving the environment, namely natural and man-made ecosystems and landscapes, have created an increased need for integrated, participative and scalable solutions focusing the various levels of irrigation and nature water management, from the field crop to the catchment and basin scales. Meanwhile, challenges and issues relative to water management for agriculture and food have evolved enormously in the last 30 years and the role of active management of the components of the water cycle is assuming an increased importance since their dynamics are key to assure water use sustainability, mainly agriculture and natural ecosystems sustainability. However, different regions face context-specific challenges associated with water scarcity, climate, governance, and population requirements. The main and first challenge is producing enough food for a growing population, which is intimately related with challenges placed to agricultural water management, mainly irrigation management. This paper revises challenges and progress achieved in the last 30 years focusing on irrigated agriculture, mainly water management, and its contribution to food security and the welfare of rural communities.

“…The potential of anaerobic digestion to produce biogas is presented by Houdková [17] -authors present biogas production in laboratory and next comment potential of biogas utilization and in biogas production for vehicles. Matuszewska et al [18] evaluated the biological methane potential of various feedstock for the production of biogas to supply engines in agricultural tractors. Otherwise, biogas can feed generators producing electricity in stationary local power plants.…”

In each touristic city waste management system has to overcome the impact of visitors. Dubrovnik, famous as popular touristic destination, particularly notices tourists visiting city. Therefore potential impact of waste management in touristic cities, such as Dubrovnik, is presented. The paper includes estimation of yearly waste production by inhabitants and tourists visiting those city. Waste digestion is a method for biogas production. On the basis of the preceding estimation combined-cycle installation generating heat and electricity is proposed. The model combines Brayton cycle with low temperature Kalina model based on Rankine cycle. Literature analysis presents state of the art in this field. The simulation is prepared in Cycle-Tempo. Numerical analyses lead to technical issues, which have to be taken into consideration during waste utilization with such installation. Thus benefits and threats are discussed. The presented analysis assesses the maximal electric gain, which subsequently should consider waste preparation and purification

“…Naturally, the development of engines that adopt new technologies, fuels, or configurations requires extensive investigations to evaluate the impact on their performance and emissions. Another purpose of these investigations is to calibrate the engine operation to these new conditions (Shivapuji and Dasappa 2017; Matuszewska et al 2016). In that sense, the parametrization of data maps for optimal engine operation is defined as engine "calibration" (Grasreiner 2012).…”

This chapter reports on a workflow aimed at obtaining deeper insights into spark ignition engines using thermodynamic modelling. This workflow is divided into two steps: (i) Auto-calibration of combustion and heat transfer models using AVL Boost ® and AVL Design Explorer; and (ii) in-cylinder exergy analysis using Wolfram Mathematica ® . Model calibration is usually based on experimental pressure curve and combustion data. However, there is a gap in methods that generate accurate simulation results, while calibrating the combustion and heat transfer models without prior experimental results. Thus, the authors proposed an approach in their earlier work to address this gap. In this chapter, this proposed approach has been complemented with exergy analysis to form a complete workflow for engine research using simulation. This workflow was applied to a 4-cylinder gasoline engine template model as a case study. First, the combustion and heat transfer models are parametrized and used as design variables of an optimization problem. The objective functions in this problem are the combustion phasing, here defined as the crank angle in which the peak cylinder pressure occurs CA pp , and the mechanical load, here defined as the indicated mean effective pressure IMEP. The appropriate temperature constraints were included to guarantee that the engine model was representative of the physical problem. The optimization problem is then solved for a target IMEP and CA pp and the results are analyzed. Afterwards, we begin the exergy analysis of the engine to obtain deeper insights. The resulting curves for the thermodynamic state properties and species' molar fraction are exported from the simulation software to a program in Wolfram Mathematica that does the exergy analysis of the engine, providing deeper insights into the useful work available in the engine, losses due to heat transfer, losses in the exhaust gases, and combustion irreversibilities. This analysis can be very useful in determining the best fuel mixture, operating conditions, and areas for improvement.
