Experimental evaluation of porosity, axial and radial thermal conductivity, of an adsorbent material composed by mixture of activated carbon, expanded graphite and lithium chloride
(Applied Thermal Engineering, 2019-03-05)
In this study, an adsorbent material made up of a mixture of activated carbon, expanded graphite and lithium chloride, is proposed to evaluate its thermal properties. Ratio effect between mixing components, component ...
Combustion and performance study of low-displacement compression ignition engines operating with Diesel–Biodiesel blends
(Applied Sciences, 2020-01-30)
This study investigated the influence of different biodiesel blends produced from residual sunflower oil and palm oil from agroindustry liquid waste on the characteristics of the combustion process, performance, and emissions ...
Regenerative reassembly phenomenon in the turning process machining the A1020 steel
(Contemporary Engineering Sciences, 2018-08-01)
The chattering in the machine tools is a phenomenon that causes instability in the
machining process, surface finish with high roughness, also produces excessive
and accelerated wear on the tool in the metal cutting ...
Brake discs: A technological review from its analysis and assessmentDiscos de freno: Una revisión tecnológica de su análisis y evaluación
(Informador Técnico, 2019-10-31)
Braking systems are undoubtedly the most important component for road safety, since it determines the total or partial stop of a vehicle and, therefore, guarantees the physical integrity of passengers. Normally, the front ...
Thermal analysis of the heat exchanger used in a regenerative Brayton cycle under real working conditions
(International Review on Modelling and Simulations, 2019-12)
The quality of the energy transformation processes focuses on improving the energy efficiency of the components used in a thermodynamic cycle with the aim to upgrade the application of the resources needed to produce energy ...
Use of Bézier curves in the design of the displacement law of the cam-follower mechanism: Von Mises effective StressUso de las curvas de Bezier en el diseño de la ley de desplazamiento del mecanismo de leva - seguidor: esfuerzo efectivo de Von Mises
(Revista UIS Ingenierías, 2020-07-01)
Designing cams by Bézier Curves has become increasingly common, since the mathematical development of this
method is less complex. Bezier curves are Bernstein-based polynomials under a unitary domain, and in that sense, ...
Influence of the firing process on water absorption and compressive strength in ceramic samples
(Journal of Physics: Conference Series, 2019-11-19)
It is presents the evaluation of water absorption and compressive and flexural strength in perforated blocks manufactured in a Hoffman-type kiln of brickworks Ocaña, Colombia. Combustion gases are reused in the firing ...
Principal stresses on the contact surface of a cam-tracker mechanism designed using Bézier curves
(Contemporary Engineering Sciences, 2018-11-29)
The study exposes the variation of the main stresses in a cam mechanism with
roller follower whose profile has been designed by means of Bézier curves. The
contact theory for the cam case is proposed and the distribution ...
Thermoeconomic modelling and parametric study of a simple ORC for the recovery of waste heat in a 2 MW gas engine under different working fluids
(Applied Sciences, 2019-10-25)
This paper presents a thermo-economic analysis of a simple organic Rankine cycle (SORC) as a waste heat recovery (WHR) systems of a 2 MW stationary gas engine evaluating different working fluids. Initially, a systematic ...
