Dead time, hard time, and narrative redemption: Delimiting the life proper
Abstract Is every detail of your life a candidate for the meaningful, valuable, or worthwhile? If not, which do you exclude? Thaddeus Metz nominates “dead time”: the nail‐clipping, line‐waiting, traffic‐jam enduring, generally commonplace moments of our life. Dead time, while prevalent, is not remarkable. Metz recommends that we set at least some of it

CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings
ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Abstract Many individuals affected by the hereditary neurological condition Huntington's disease (HD) have reported experiences of stigmatization, yet the extant literature is currently theoretically and methodologically underdeveloped. Therefore, this scoping review aimed to examine the methodological approaches and theoretical conceptualizations of ...

ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...

AbstractIn Chapter 12 unsteady pipe flow is discussed by means of the method of characteristics for which the underlying basic equations are derived at first. These are the continuity and energy equations according to Alliévi and their solutions by Riemann as well as the unsteady momentum equation.

Ocean Wave Modulation of Offshore Wind Turbine Loads and Wake
ABSTRACT This study examines how wave‐induced modulation affects the operational performance and structural dynamics of fixed‐bottom offshore wind turbines operating under a neutral atmospheric boundary layer profile. To capture these effects accurately while maintaining computational efficiency, unsteady RANS modelling techniques are employed.

ABSTRACT Optimising turbine layouts to maximise power output is crucial for wind farm development, particularly in complex terrain where analytical wake models fail to capture key flow physics. We present the first application of Bayesian optimisation (BO) combined with large eddy simulations (LES) for utility‐scale wind farm layout optimisation in ...

Comparison of Power and Thrust Performance for a Fixed and Floating Offshore Wind Turbine
ABSTRACT Floating offshore wind turbines have been identified as a critical technology for sustainable electricity generation. Wind resource assessment is used to determine optimal locations for floating wind farms. However, current methodologies do not account for performance differences between fixed and floating turbines due to wind‐ and wave ...
