Exergoeconomic optimization of a district cooling network

The exergoeconomic model of a district cooling network was used to calculate the costs of cold at the primary side of the consumer. Two different types of pipes were considered in this analysis: pre-insulated steel pipes, where polyurethane was considered as an insulation material, and polyethylene pipes, without insulation.

Slippage of Thermal Insulation Subjected to Seismic Load

doubled the friction coefficient compared to the similar insulation systems with the usual upper surface. This might be useful for the protection of the building against slippage when it is subjected to the seismic load. Insulation systems with grooves always transferred possible slippage at the level of the levelling

Modeling of Unsteady Friction and Viscoelastic Damping in

PDF | In real systems, the phenomena, such as pipe-wall viscoelasticity, unsteady friction or fluid structure interaction induce additional damping and dispersion of transient pressure waves than that defined by classical waterhammer. In this paper, unsteady friction models

Puncture Resistance | Plastic Testing Physical Properties

Puncture resistance is a measure of the maximum force or energy required to penetrate a material. This type of biaxial stress is seen by packaging films when packing hard protuberances such as pelleted dry foods and frozen vegetables.

PPI TR-47 - Pipe Stiffness and Flattening Tests in

HDPE conduit has been used for decades with great success due to its low coefficient of friction, resistance to corrosion, excellent chemical resistance and Guidelines for Use of Mini-Horizontal Directional Drilling for Placement of High Density Polyethylene Pipe.

Coefficient of Friction | Plastic Testing Physical

Static friction is the force needed to create movement between two surfaces. The coefficient of friction is a critical property of all materials which run on high speed manufacturing lines; particularly those in the printing and packaging industry. Coefficient of friction is routinely specified for plastic flowrapping films.
