Role of resonances on microwave heating of oil–water emulsions

Role of metallic and composite (ceramic–metallic) supports on microwave heating of porous dielectrics

“…Similar assumptions are also found in earlier literature [5][6][7][8][9][10][11]. The wave propagation due to uniform electric field, E x , obtained from Maxwell's equation is…”

“…E t;1 ¼ E 0 and E r;n ¼ 0, Eq. (6) are solved for the remaining 2n À 2 coefficients using MATLAB [7,8,10]. For the lth layer, the transmitted and reflected waves are…”

“…At the interface node, the field variable and fluxes are continuous as discussed by Reddy [27] and Ayappa et al [1]. To discretize the time domain, Crank-Nicholson method is used, and the nonlinear residual equations are solved using Newton Raphson Method [7,8]. Due to the lack of a good initial guess to begin the Newton scheme, a small time step Dt ¼ 1Â 10 À4 s was used in the first step.…”

“…At a resonant condition the average power absorption within the sample is a local maximum and the effect of sample size on enhanced microwave heating rate was analyzed in the presence of resonances by Barringer et al [3] and Ayappa et al [4]. Microwave heating and transport models were further applied for thawing and heating of multiphase systems in recent investigations [5][6][7][8][9] and greater rates in material processing were observed due to resonances. All these earlier works on heating and melting were carried out to investigate the heating effects solely due to the materials.…”

Penentuan Kelayakan Fungsi untuk Pemodelan Pemanasan Minyak Mentah menggunakan Energi Gelombang Mikro

“…Energi panas ini akan meningkatkan suhu crude oil dan menurunkan nilai viskositas sehingga lebih mudah untuk dialirkan. Hal lain yang menjadi kelebihan energi gelombang mikro ini adalah proses pemanasannya yang bersifat volumetrik, lebih cepat, efektif, dan efisien [4].…”
