Utilizing the high birefringence and low-temperature coefficient of highly birefringent photonic crystal fiber (HiBi-PCF), a temperature-insensitive interferometer made from HiBi-PCF loop mirror (FLM) is achieved. For wavelength spacing 0.43 nm, variation with temperature only 0.05 pm//spl deg/C, transmission peak shift 0.3 deg/C demonstrated. The stability FLM improved dramatically when it uses HiBi-PCF, as compared to FLMs using conventional HiBi fibers.
This paper reports on a textile fiber optic microbend sensor for heartbeat and respiration monitoring. A section of multimode optical sandwiched between parallel strips acting as microbender is being integrated onto an elastic substrate. Its design based microbending effects. The can be used to measure rate simultaneously during standing sitting position. detected heart rates from our are in good agreement with that the commercial SpO2, whereas verified by counting breathing manually. We...
We propose and demonstrate the feasibility of using a highly sensitive microbend multimode fiber optic sensor for simultaneous measurement breathing rate (BR) heart (HR). The sensing system consists transceiver, fiber, computer. transceiver is comprised an optical transmitter, receiver, circuits data communication with computer via Bluetooth. Comparative experiments conducted between predicate commercial physiologic devices showed accuracy ±2 bpm both BR HR measurement. Our preliminary study...
A novel and simple sensor based on a 3/spl deg/ slanted multimode fiber Bragg grating (MFBG) for simultaneous temperature refractive index measurement is demonstrated. The MFBG shows two wavelength groups in its transmission spectrum: One group, due to the coupling from one core mode cladding modes, sensitive both surrounding (SRI) other, other modes only temperature. Utilizing obvious difference of dips different index, parameters can be distinguished measured simultaneously using MFBG.
Smoothed particle hydrodynamics (SPH) is a popular meshfree Lagrangian method, which uses kernel function for numerical approximations. The closely related to the computational accuracy and stability of SPH method. In this paper, new proposed, consists two cosine functions referred as double function. newly proposed sufficiently smooth, associated with an adjustable support domain. It also has smaller second order momentum, therefore it can have better in terms approximation. method applied...
The smoothed particle hydrodynamics (SPH) method has been increasingly used for simulating fluid flows; however, its ability to simulate evaporating flow requires significant improvements. This paper proposes an SPH multiphase flows. present can the heat and mass transfers across liquid-gas interfaces. conservation equations of mass, momentum, energy were reformulated based on SPH, then govern transfer in both liquid gas phases. continuity equation vapor species was employed fraction phase....
Smoothed particle hydrodynamics (SPH) is a Lagrangian meshfree method. It has special advantages in modeling large deformation and free surface flow, been widely applied to different problems engineering science. However, the classical SPH suffers from stress instability which resticts its further development applications. The fundamental reason of that state kernel do not match each other. For frequently used bell-shaped function, tensile attraction between particles increases as spacing...
Abstract The Gulf Stream system features some of the fastest and most persistent currents in Atlantic Ocean has long been identified as a promising target for renewable ocean current energy. This study investigates theoretical energy potential system. A simplified analytical model is calibrated utilized to represent quasi-geostrophic balance North subtropical circulation. effect turbines included additional turbine drag force. equation derived analyzed both locally basin-wide. Basin-wide,...
This paper presents a smoothed particle hydrodynamics (SPH) and element bending group (EBG) coupling method for modeling the interaction of flexible fibers with moving viscous fluids. SPH is well-developed mesh-free simulating fluid flows. EBG also bodies. The fluids rendered through particles fiber fluid. In numerical simulation, different lengths are immersed in driven by body force. drag force on obtained from SPH-EBG simulation agrees well experimental observations. It shown that...
