Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Glazing Effects on Dynamic‐Insulation TSC Façades: A CFD‐Supported Experimental Study of Flow, Heat Transfer, and Ventilation Preheating

Energy Science &Engineering, EarlyView.
Glazed transpired solar collectors achieve 48–75% efficiency and 11% more seasonal heat than unglazed designs by cutting convective losses, while both offer complementary benefits for ventilation preheating and dynamic wall insulation, with paybacks of 5.5–6.8 years.

Skewness of Impinging Cooling Blockage Jet

Applied Sciences
Building upon our previous aerodynamic characterizations of skewed jets, this study extends the investigation to systematically evaluate their thermal performance. Turbulent air jets are produced by unilaterally supplying coolant and forcing it through a series of concave perforated blockages having varying relative inner diameters (Din/Dj = 3.0, 4.0 ...

Flammability of Facades Across Scales and International Standards

Fire and Materials, EarlyView.
ABSTRACT Facade fires are a rare but destructive hazard that can lead to the rapid spread of fire between the floors and fire compartments of a building. Today, there are at least 21 different national standards for facade fire tests in use around the world, which seek to categorize facades based on their flammability.

Numerical Investigation of Spray Impingement Heat Transfer in the Film Boiling Regime

Fluids
Spray impingement cooling is a well-established heat removal technique employed across a wide range of industrial processes. A particularly significant cooling regime arises when the temperature of the cooled surface surpasses the Leidenfrost temperature

Study of Damage to Shutters Exposed to a Vegetation Fire: Definition of Vulnerability Thresholds

Fire and Materials, EarlyView.
ABSTRACT This study examines the fire behavior of wooden, PVC, and aluminum shutters through laboratory and large‐scale experiments. Laboratory tests were conducted using a cone calorimeter to assess the ignitability of the PVC and wooden shutters, focusing on the critical heat flux of ignition, ignition time and critical Flux Time Product (FTP ...

Fire Spread Characteristics of Cavities in Modular Constructions and Ventilated Facades

Fire and Materials, EarlyView.
ABSTRACT Modular buildings have gained popularity as a sustainable building solution. However, the uncertainty of fire spread through vertical cavity spaces in such buildings has become a concern. Therefore, this study aims to fill the gap in fire behaviour within vertical cavity spaces.

Treatments for femoroacetabular impingement [PDF]

The hip is a ball and socket joint in which the femoral head (the ball) articulates with the acetabulum (the socket). In a condition called femoroacetabular impingement (FAI) the hip has a shape abnormality and is no longer perfectly spherical. The hip
