Effectiveness - NTU data and analysis for air conditioning and refrigeration air coils
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2010)
A simulation program based on a control volume analysis has been used in the evaluation of the (ε, NTU) relationship for coils of complex geometry and flow arrangement. The simulation program has been evaluated through ...
Air core notch-coil magnet with variable geometry for fast-field-cycling NMR
(Academic Press Inc Elsevier Science, 2015-10)
In this manuscript we present details on the optimization, construction and performance of a wide-bore (71 mm) α-helical-cut notch-coil magnet with variable geometry for fast-field-cycling NMR. In addition to the usual ...

Two-phase flow frictional pressure drop prediction in helical coiled tubes
(Pergamon-Elsevier Science Ltd, 2020-12)
Based on the construction of different experimental databases, the frictional pressure drop in helical tubes for single-phase and water-steam two-phase flow was analyzed empirically. The aim of the present study is to ...
Levenberg-Marquardt application to two-phase nonlinear parameter estimation for finned-tube coil evaporators
(Hindawi Publishing Corporation, 2006-01-01)
A procedure for calculation of refrigerant mass flow rate is implemented in the distributed numerical model to simulate the flow in finned-tube coil dry-expansion evaporators, usually found in refrigeration and air-conditioning ...

Determinação da frequência de autorressonância por onda estacionária em enrolamentos solenoidais e proposta de um sistema autorresonante de transferência de energia sem fio utilizando bobinas bifilares abertas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2016-10-25)
Common in electrical engineering projects, air-core single-layer solenoid coils can present self-resonant frequencies due to stationary waves effects. The comprehension and determination of these frequencies is of primordial ...
