摘要

Abstract <section xml:id="jctb5484-sec-0001" numbered="no"> <title type="main">BACKGROUND >Tubular photobioreactors (TPBRs) have great potential in culturing microalgae, but their poor mixing properties make it difficult to increase the surface productivity. In this work, a TPBR with inserted self‐rotating helical rotors, which have been under study for a decade, was designed. </section> <section xml:id="jctb5484-sec-0002" numbered="no"> <title type="main">RESULTS > This paper aimed to show hydrodynamic behaviors of gas–liquid in a TPBR with inserted self‐rotating helical rotors by computational fluid dynamics (CFD) and visualization experiments. It can be concluded that by assembling self‐rotating helical rotors into the TPBR, very remarkable mixing and particle cycle frequencies were achieved. Besides, the influences of rotor lead and liquid inlet velocity on the swirl number, the gas and liquid average circumferential velocities, pressure loss, cell trajectories and shear stress were also investigated. The best choice was to select a rotor lead of 150 mm and a liquid inlet velocity of 0.4–0.5 m s ‐1 for microalgae with strong shear force tolerance. Microalgae cultivation experiments verified that helical rotors had a positive effect on biomass productivity. </section> <section xml:id="jctb5484-sec-0003" numbered="no"> <title type="main">CONCLUSION >The results indicated that assembling the self‐rotating helical rotors into TPBR was a feasible and effective method to improve the mixing performance and microalgae productivity. ? 2017 Society of Chemical Industry </section> </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>抽象</ title> <section XML：ID =“JCTB5484-SEC-0001”编号=“否”> <标题类型=“main”>背景</标题> >管状光生物反应器（TPBR）在培养微藻中具有很大的潜力，但它们较差的搅拌特性使其变得困难提高表面生产力。在这项工作中，设计了一个带有插入的自旋转螺旋转子的TPBR，该TPBR已经在十年中进行了研究。</ p> </ section> <第XML：ID =“JCTB5484-SEC-0002”编号=“。否“> <标题类型=”main“>结果</ title> >本文旨在通过计算流体动力学（CFD）和可视化实验来显示TPBR中的TPBR中的气液的流体动力学行为。可以得出结论，通过将自旋转螺旋转子组装到TPBR中，实现了非常显着的混合和颗粒循环频率。此外，还研究了转子铅和液体入口速度对旋流号，气体和液体平均圆周速度，压力损失，细胞轨迹和剪切应力的影响。最佳选择是选择150mm的转子引线和液体入口速度为0.4-0.5m S -1 -1 -1 / sop>，用于微藻，具有强的剪切力耐受性。微藻培养实验证实，螺旋转子对生物质生产率具有积极影响。 </ p> </ section> <部分XML：ID =“JCTB5484-SEC-0003”编号=“否”> <标题类型=“main”>结论</ title> >结果表明组装自我 - 进入TPBR的螺旋转子是一种可行且有效的方法，可以提高混合性能和微藻生产率。还2017年化学工业协会</ p> </段> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-33908/'>《Journal of Chemical Technology & Biotechnology》</a> <b style="margin: 0 2px;">|</b><span>2018年第5期</span><b style="margin: 0 2px;">|</b><span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Yan Hua&option=202" target="_blank" rel="nofollow">Yan Hua;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Guan Changfeng&option=202" target="_blank" rel="nofollow">Guan Changfeng;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Jia Yuchuan&option=202" target="_blank" rel="nofollow">Jia Yuchuan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Huang Xinxue&option=202" target="_blank" rel="nofollow">Huang Xinxue;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Yang Weimin&option=202" target="_blank" rel="nofollow">Yang Weimin;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Beijing University of Chemical TechnologyBeijing P.R.
