Geometric design of micro scale volumetric receiver using system-level inputs: An application of surrogate-based approach
(Elsevier, 2023-09-15)
Concentrating solar thermal power is an emerging renewable technology with accessible storage options to generate electricity when required. Central receiver systems or solar towers have the highest commercial potential ...
On the low-cycle fatigue behavior of a multi-phase high entropy alloy with enhanced plasticity
(Elsevier, 2023-08)
A multi-phase non-equiatomic FeCrNiMnCo high entropy alloy (HEA) was fabricated using vacuum induction melting. Thermo-mechanical treatments consisting of cold rolling and annealing at 750 °C and 850 °C were employed to ...
Off-design performance of micro-scale solar brayton cycle
(Elsevier, 2023-08-01)
A novel methodology to design a micro-scale, solar-only, air-breathing, open Brayton cycle and assess its on- and off-design performance. The methodology is applied to generate and assess six thermodynamic layouts over a ...
Design and control of a novel variable stiffness series elastic actuator
(IEEE, 2023-06)
This article expounds the design and control of a new variable stiffness series elastic actuator (VSSEA). It is established by employing a modular mechanical design approach that allows us to effectively optimize the ...
An experimental study on the frost formation over a flat plate: Effect of frosting on heat transfer
(Elsevier, 2023-06-01)
Frost accumulation on cooled surfaces generates thermal barrier between the surface and air. Apart from the frost layer thickness, the thermal properties of the frost also affect its heat transfer characteristics. In this ...
Combining tensile test results with atomistic predictions of elastic modulus of graphene/polyamide-6,6 nanocomposites
(Elsevier, 2023-06)
In this work, we combined tensile test results with atomistic simulations to investigate the effect of filler parameters including distribution, stacking, loading and lateral graphene size on elastic moduli of graphene/PA-6,6 ...
A novel design framework for generating functionally graded multi-morphology lattices via hybrid optimization and blending methods
(Elsevier, 2023-05-25)
Owing to its excellent mechanical properties, triply periodic minimum surfaces (TPMS) lattice structures have recently gained more interest in engineering applications. The superior properties of these structures make it ...
Enhancing the performance of Piezoelectric Energy Harvester under electrostatic actuation using a robust metaheuristic algorithm
(Elsevier, 2023-02)
This study proposes a novel shape optimization methodology based on evolutionary algorithms to maximize the harvesting energy from piezoelectric energy harvester stimulated by the β-emitted radioisotope. The parametric ...
Contact force distribution using centroidal momentum feedback for quadruped locomotion
(IEEE, 2023)
This paper proposes a method to distribute contact forces to eliminate undesired torso orientation fluctuations and regulate heading during dynamic quadruped trot-walking motion. The proposed method makes use of centroidal ...
Swelling phenomenon in rubber weatherstrip manufacturing under real process conditions imposed in a commercial extrusion line
(Springer, 2023-01-06)
We investigated the swelling under different process and boundary conditions in a commercial weatherstrip extrusion line. For the experimental investigations, we used two extrusion-dies and three compounds. An in-situ laser ...
