Understanding sludge rheology and optimizing equipment performance is crucial for energy efficiency in wastewater treatment plants (WWTPs). This study examined sludge rheology after thermal hydrolysis pretreatment (THP) at 60, 80, and 120 ◦C for 2 h, followed by anaerobic digestion (AD) at 37 ◦C for …

Purpose: The aim of this study was to asses if a combination of events related to injuries (surrogate measures) in Ski Cross (SX) is more likely to lead to crashing than one surrogate measure and how it differs between male and female athletes. Method: The data collected by using video analysis on the …

This Powerpoint is part of the project Twomes. This deliverable contains a presentation about the heat balance model and inverse-grey-box analysis tools that support automated estimation of crucial parameters of buildings, installations and comfort needs in individual homes and utility buildings based …

In practice, faults in building installations are seldom noticed because automated systems to diagnose such faults are not common use, despite many proposed methods: they are cumbersome to apply and not matching the way of thinking of HVAC engineers. Additionally, fault diagnosis and energy performance …

The Heating Ventilation and Air Conditioning (HVAC) sector is responsible for a large part of the total worldwide energy consumption, a significant part of which is caused by incorrect operation of controls and maintenance. HVAC systems are becoming increasingly complex, especially due to multi-commodity …

District heating (DH) has a major potential to increase the efficiency, security, and sustainability of energy management at the community scale. However, there is a huge challenge for decision makers due to the lack of knowledge about thermal energy demand during a year.  https://www.mdpi.com/1996-1073/14/17/546 …

Increasing urbanization and the effects of climate change will bring new challenges for cities, such as energy saving and supply of renewable energy, preventing urban heat islands and water retention to deal with more frequent downpours. A major urban surface, the surface of roofs, is nowadays hardly …

Eén van de doelstellingen van het onderzoeksproject Flexiheat is het ontwerpen van innovatieve business modellen die een succesvolle exploitatie van warmtenetten stimuleren door het benutten van flexibiliteit. Binnen Flexiheat is het Energy Transition Park in Wijster met de afvalverbrandingsinstallatie …

Balancing of the heat and electricity network as it is done nowadays and relevant challenges that need to be faced in the future, with the increase in intermittent renewable energy sources that produce energy on decentralized scale levels.

Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning …
